♪ ♪ NARRATOR: Like many of his era, Chris grew up with the American Dream: the dream of a steady job, a reliable income, and a golden retirement.

And each new generation would have a better life than the previous generation.

DEREK THOMPSON: The American Dream is this dream of constant progress.

This idea that in America, your station of birth is not your destiny.

That you can be born poor, but your biology and your family and your networks, they aren't as important as what you put into your life.

That effort can overcome anything.

♪ ♪ NARRATOR: Francis's hope for a comfortable retirement has evaporated.

Later in the series, his story continues.

How will he fare in this disrupted landscape?

For now, he is part of the new precariat, a rising tide of workers who survive from one short-term, low-paid job to the next.

TYSON: There are many ways-- your income's precarious, your benefits precarious.

You don't have a long-term link to the customer for whom you're providing the service.

It's precarious employment.

NARRATOR: But not all short-term jobs are low-paid.

CHLOE GRISHAW: TaskRabbit is an app and a website that connects taskers and clients to do odd jobs, which we call tasks.

Anything from furniture assembly to errands to organization.

I'm Chloe.

For four years, I've used TaskRabbit.

From my side, as a tasker, I would open the app and mark off my availability, and then-- hopefully-- I get a client who books me in that time.

They describe the task that they want done, how long they think it would take, and then book them on the schedule, and then show up.

♪ ♪ NARRATOR: There is a new gig economy fueled by technological advancements.

It operates through digital platforms like Uber, Lyft, and TaskRabbit.

TYSON: The gig worker has grown out of the use of company platforms.

What the person is doing is looking for customers.

What the platform is doing is linking them to customers.

GRISHAW: What I love about TaskRabbit is that it's really flexible.

I set my own schedule, I set my own rates.

I know what I'm agreeing to.

NARRATOR: For both clients and workers, there are no long-term obligations.

When the job is done, the relationship is over.

GRISHAW: Work and the way that we see work is changing.

It's no longer this rigid, like, 9-to-5 idea.

It's a lot more flexible, and apps definitely give you that sense of freedom and flexibility.

Any spare time you have, you can start earning income during those times, which is definitely different from your traditional, "I have one job and that's the only basis of income."

NARRATOR: Today, more than 55 million Americans work in the gig economy.

For some like Chloe, it provides flexibility and freedom.

For others, it introduced even more financial insecurity.

So there's almost two Americas that exist right now: this America that feels basically safe, and can think about things besides paying their bills, and an America that is constantly afraid.

And so, for those people, the gig economy is not liberation-- it's just survival.

It's a way to make ends meet when your regular job has already failed you.

JOHN RUSSO: The work is being further fragmented in terms of part-time, full-time, independent contractors, gig work.

Part of the people are saying, "Well, isn't this great?

People have more freedom."

On the other hand, I'd like to talk to them after five or ten years to see where they are economically when they have no health insurance and no pension.

DAVID SIEGEL: There is a big difference between a job and a career, and this distinction is being lost in our society.

A career is something that will serve you for your lifetime, and it's very meaningful.

Jobs, on the other hand, are very transactional.

The gig economy makes jobs really transactional.

COVID has put a lot of businesses, you know, out into pasture, because it made just an uncertainty of everything that's going on.

You know, one day, you're making gangbusters money, and then coronavirus hits, and now you're not making any money.

NARRATOR: With over 100,000 pandemic-driven closures, one in six restaurants across the country were shuttered.

While many restaurants may never reopen, by spring 2021, hiring had resumed among those that remain.

ABBOTT: Yeah, we're here on U Street, and pretty much the place closed down in every block.

But mine was, we had to stay open.

And then we kind of just went with shortened staff and, you know, tightened our belts.

How you doing, my friend?

Come on in.

Our people have always been resilient.

I'm used to not having and doing without, and I had to decide, you know, what we were going to do as far as the daily business and the daily grind.

Are you going to pick up the delivery and the first responders?

And are you going to market a little bit better?

Make COVID specials?

I mean, you had to come up with some great ideas for you to survive through the pandemic.

My grandmother would say, "You know what?

"If you can make something today, it's better than making nothing today."

So we, we just focused on, on making something rather than nothing.

NARRATOR: Restaurant like Oji's survive because they were able to embrace the new world of remote ordering, deliveries, and social distancing.

The trend towards technology-enabled remoteness has taken off across many industries.

COVID is a very complicated thing to sort through.

It has demonstrated that for tens of millions of jobs, it's possible to do those jobs effectively remotely, at least for a period of months.

THOMPSON: I think the pandemic has fundamentally been an accelerator.

I think it's taken a lot of things that were changing very slowly and it's changed them very quickly.

So you look at something like remote work.

It wasn't happening in the '80s, it wasn't happening in the '90s.

It wasn't happening in the 2000s.

But just in the last five years, you've started to see little tiny bits of evidence that remote work was starting to pick up, and then, of course, with COVID, it absolutely took off and accelerated, taking a trend that had already been invented and putting it on steroids.

NARRATOR: This acceleration of new forms of remote work, along with many other transformations, has been made possible by digital technology.

As it displaces some jobs and creates others, digital technology is at the heart of the new industrial revolution.

♪ ♪ CARLOS GUTIERREZ: We are in a digital revolution where everything is being displaced by digital technology.

Technology has taken over our lives and it will continue to do so.

So we're going to have to run very fast in order to keep up with it.

♪ ♪ NARRATOR: This is not the first time technology has profoundly disrupted the landscape of work.

♪ ♪ In the 19th-century industrial revolution, millions of jobs in agriculture and crafts disappeared.

Eventually, they were replaced by other work in factories.

Throughout the 20th century, new technologies upended industry after industry.

Jobs were lost, only to be replaced by new kinds of jobs.

Throughout the centuries, in technological revolution after technological revolution, work and workers have survived.

Will it be the same this time around?

THOMPSON: Agriculture is a great example of how fast the work force can change.

200 years ago, more than nine in ten Americans worked in agriculture.

Today, about one to two in 100 Americans work in agriculture.

It's gone from 90% of the economy to about 1.2, 1.6% of the economy.

But we're not starving.

We're eating more, we're eating better.

We're eating more healthily than we did 200 years ago because of technology.

And so I think that agriculture can offer both an element of fear and an element of hope.

♪ ♪ ♪ ♪ SARAH LOVAS: Technology has completely changed the way that farmers do things today.

It's changed everything from the seeds that we plant to the way that we drive our equipment.

My name is Sarah Lovas and I'm a farmer.

My family's been farming in North Dakota for four generations.

NARRATOR: In the 80 years that Sarah Lovas's family has been farming, cities exploded, and the rural population declined from 70% of all Americans to just 15%.

As new farming technology replaced workers, there was an exodus from the countryside.

Today, there is a farm labor shortage.

Farmers have embraced the latest technologies because they have to.

JAKE JORAANSTAD: You get in a tractor cab today and there's literally three to five screens.

And they're running all kinds of different technologies in the tractor and on the farm.

LOVAS: In my life, the two greatest advances that have affected agriculture include biotechnology and also GPS on our tractors.

As a matter of fact, we don't even hold the steering wheel when we're in the, in the tractor cabs anymore.

So you notice I'm not steering.

No hands!

That's because the GPS is actually steering the combine right where it needs to be, and it allows us to stay within a two-inch accuracy of being on this line that we told the computer that we want to be on.

We hook it up to the auto-steer and the GPS guides the tractor, and the tractors literally drive themselves until they get to the end of the field, and then we turn the tractor around and send it back the other direction.

Even my father-in-law, who's been farming for more than 50 years and has seen so many changes over his lifetime, he knows how to run the computers in there to get auto-steer to work correctly.

Because it's just what we have to do today.

JORAANSTAD: The solutions being driven with technology today are to create a way for the local farmer, the small farmer, the family farmer to be able to actually do more with less because they don't have the labor to come to the farm today and help.

CAMILLE GRADE: There is a tech revolution that's happening in farming, and you see it all around us.

Agriculture is being digitized.

I work at an ag tech company located in Fargo, North Dakota, one of the most productive regions in the world in terms of commodities.

The digitization of agriculture, it's created job opportunities for those that surround the farmer that weren't there before.

We can help with farmers using tools through their smart phones to take advantage of the digitization.

♪ ♪ There are irrigation pivot systems that, farmers can now open their phone and they can change the pivot on the system right from there.

NARRATOR: Even with sophisticated technology, economics often work against the small farmer.

♪ ♪ Most of the profits in agriculture go to corporations supplying seed and equipment.

They also go to the agribusiness giants that distribute agricultural products around the world.

Farmers know they are small cogs in a worldwide marketplace.

LOVAS: It's very global.

We produce food for everybody in the United States, but we produce food for the whole world.

China, Taiwan.

We have hosted a Korean trade group on this farm before.

NARRATOR: The globalization of agriculture gives farmers access to distant markets.

But it also exposes them to global commodity price fluctuations.

LOVAS: 2018 and 2019 are two years back-to-back that have actually been very challenging economically for farms in this area.

♪ ♪ The commodity prices are low and inputs are expensive.

Since then, I'm happy to report that the prices have come back and we are actually hoping to maybe break even.

But keep that in mind, we're hoping to maybe break even.

MARK WATNE: We're a little stubborn up here.

We want to prove that we can do it.

We're eternal optimists, in a sense, where we believe things can get better.

And, and at times, they do get better.

It's, it's not always doom and gloom.

It's, it's a cyclical thing.

Seems like we live in the doom and gloom more than in the, in the good time.

NARRATOR: Despite the many technological advances in agriculture, farmers still have to live with high degrees of uncertainty.

So farm stress is a very real thing now.

And in the last three to five years, the farmer suicide rate has actually increased quite a bit in North Dakota.

Oftentimes, our culture in rural America is to be stoic, and you just tough it out and get through it.

And this is pretty tough.

For... Again, we've got four generations into our farm.

Where's the big tire?

BOY: Right there!

LOVAS: Big tire!

Where's the bucket on your tractor?

(boy babbling) LOVAS: Where's the seat?

BOY: Seat!

LOVAS: Where's the engine?

BOY: Engine!

LOVAS: We have a young son whose first word was tractor.

What's this?

Hm?

- Tractor tractor.

- Is that your trac-tractor?

He loves the farm, he loves being out here.

Can you show me... - All done!

- All done!

MAN: Go combine!

LOVAS: Okay, go combine!

Should he choose to farm, he would be the fifth generation.

And that's something that's a big, a big burden, I think, for farmers to carry on their shoulders.

When you've got generations behind you and generations in front of you, you don't want your farm to fail on your watch.

Ooh, dump truck.

And so the Navy has gone to that across the board now.

These were people that would use calculators to tabulate numbers.

All of these jobs are gone.

A.I.

Automation has been really turbocharged by A.I.

(horns honking) NARRATOR: And for those middle-income jobs which cannot be replaced by A.I.

or automation, many can be outsourced to other countries where labor costs less.

Offshoring and automation, definitely, I think of as two of the Bash Brothers that have sort of taken on the American workforce-- that offshoring takes jobs out of the United States and puts them in countries like Vietnam, and China, and places in Africa.

RUSSO: That's why there's a lot of interest right now in the term "re-shoring."

These are the jobs that are coming and these are the jobs that are here to stay.

♪ ♪ Domestic workers often live and work in the shadows of the economy.

♪ ♪ They are mostly women.

They're working behind closed doors, in the privacy of someone else's home.

So what this then leads to is conditions that are really ripe for abuse and exploitation.

♪ ♪ There are so many dimensions to how this can be a dangerous and unsafe job.

NARRATOR: With help from organizations like the Domestic Workers Alliance, Adelaide Tembe has found her feet in the U.S. After long struggles, she's created a life for herself and her daughter.

TEMBE: I'm just keeping myself moving and to stay positive every day and look for more houses to clean.

(laughs) ♪ ♪ NARRATOR: Many types of work will survive both the pandemic and the new industrial revolution.

Many will not.

The economy is in profound transition.

As old types of work disappear and news ones emerge, the landscape remains uncertain.

TYSON: This period of transition can be extremely painful for those whose jobs are disappearing.

It can be decades.

For some workers, it's a lifetime.

They never find employment at the same level of security and wages as what they lost.

They just do not.

NARRATOR: The recent history of the Rust Belt is a reminder of just how painful these transitions can be.

For over a hundred years, Western Pennsylvania and Ohio were the heartlands of American steel and manufacturing.

Cities like Youngstown boomed.

There was a job for everybody.

Then automation and outsourcing rapidly disrupted these industries.

SHERRY LINKON: Youngstown is a great example of a place where the idea of the American Dream was very clear: you get a good job in the mill, you buy a small house, you have a comfortable, settled, predictable life, and you can do that job for all of your life.

♪ ♪ All of that sort of went away.

(distant explosion) ♪ ♪ RUSSO: And between 1977 and 1987, you had the loss of 50,000 steel and steel-related jobs.

These were middle-class jobs, jobs that had pensions, jobs that had healthcare.

And suddenly, they were thrust into unemployment, under-employment, leaving the area to find work.

And what really happened is, the community lost its sense of self.

Youngstown's story is America's story.

What happened there was the warning to what has happened in a lot of other places, as the nature of people's work lives, the nature of their economic lives, the nature of their community lives shift in ways that they have no control over, that are not about whether they've done a good job or not.

♪ ♪ THOMPSON: Youngstown is an absolutely tragic story.

Youngstown is, unfortunately, the perfect example of what happens when the heartwood of a city or town's workforce disappears because of technology or globalization.

And what you see is that the effect isn't just economic, it's psychological.

LINKON: We saw increases in alcoholism, and drug use, and domestic abuse, and depression, and suicide.

That's the measurable stuff.

What we know, too, is that a lot of people felt a sense of defeat and frustration.

LEE: We've kind of created a society where people depend on having their work to feel that they have a strong reason to exist, and then reason to live.

And the dream-- you know, whether it's the American Dream or Chinese Dream or whatever-- it has to do with, hard work is the essence of your existence, and that's the most important thing.

♪ ♪ It's very much a problem now, because people will not only come to realize the work that they've taken pride in doing could be done better, easier, and definitely cheaper by automation and artificial intelligence.

♪ ♪ NARRATOR: Cities like Youngstown represent the devastating aftermath when jobs go away.

But Pittsburgh, just 70 miles away, tells a very different story.

Having also endured the death of the steel industry, the city is now booming.

THOMPSON: Pittsburgh is a great example of diversification.

You can't just trust that the industries of the 1960s are going to be the leading industries of the 2000s.

You have to expect that change will be the norm.

And the best way to be prepared for change is to, I believe, invest in this diversification of the workforce.

♪ ♪ NARRATOR: Because of huge investments in universities and research, today, Pittsburgh is a world leader in robotics and precision engineering.

Uber's self-driving cars and Mars rovers have been pioneered here, along with countless innovations in medical technology.

♪ ♪ High-tech start-ups have fueled a demand for a new generation of precision machinists.

♪ ♪ NEIL ASHBAUGH: Pittsburghers in general, people in Western PA, really, really enjoy making things.

♪ ♪ We have a culture of producing things and bringing value to components and to products for the world.

It's still very exciting, and what we're seeing now is, different industries come up from our work in manufacturing.

PAUL ANSELMO: You talk about robotics, but what are robots made of?

A lot of different parts.

Who makes those parts?

Machinists.

♪ ♪ The future is very bright here in Pittsburgh.

♪ ♪ We've got a lot of new technologies and new industries that are coming up in the region.

♪ ♪ But it'll be machinists that will bring those products to reality and to life.

♪ ♪ NARRATOR: At least for now.

♪ ♪ The differing fates of Youngstown and of Pittsburgh suggest that technological upheavals in the world of work do not lead to one inevitable outcome.

JESUTHASAN: I think so much of the narrative for the last five to ten years has been very binary.

You've got the pessimists who would say, "Look at artificial intelligence, "look at machine learning, look at robotic process automation, and look at all of these jobs that it's going to destroy."

And then the optimists will talk about, "Well, look at how many jobs "the App Store created, look at how many new jobs are created by emerging technology."

And they'll point to the fact that throughout history, as automation has come about, there has been a net gain in employment.

NARRATOR: Robotics, artificial intelligence, and the other hallmarks of the new industrial revolution are here to stay.

How they are deployed, now and in the future... ♪ ♪ ...is an open and critical question.

♪ ♪ SIEGEL: It's all about pride and contribution.

I really believe that this is a basic human need.

And so as we design future work-- and remember, we get to design what work is, it doesn't just happen to us; the nature of work is designed by humans-- we have to design things that are useful to society, but also provide satisfaction to the basic human needs that we have.

♪ ♪ NARRATOR: To what extent society will be successful in designing work that responds to basic needs remains to be seen.

But one thing is certain: seismic changes are underway in the world of work.

Some will forfeit longtime careers.

Others will enhance ways of getting work done.

And still others will create jobs not yet envisioned.

And in this new industrial revolution, there will be winners and losers.

So how best to prepare for this unsettled landscape?

On the next episode: how to stay relevant in tomorrow's job market-- getting ready for the future of work.
