We reflect on what economics can teach us about work, technology, and the future. A new report by LinkedIn found that one in five Americans now work in jobs that didn’t exist in 2000. We consider the economic implications of new roles driven by technology, the gig economy, and changing workplace demands. We touch on the decline of now-obsolete jobs, and question how educators can help students prepare for an unpredictable employment future.

In this episode, we discuss:

* The surprising stat that 1 in 5 Americans have jobs that didn’t exist in 2000

* What kinds of new jobs have emerged in the past 25 years

* The decline of older job types and industries, like video rental

* How institutions and firms adapt to new tech by creating new roles

* Teaching strategies to help students understand labor market changes

* And a whole lot more!

Some show notes:

We’re sitting down in the middle of December, which means our classes are nearly over. By the time you’re reading this, grades have been posted, and we likely have auto replies on our emails. Jadrian celebrates the end of the term with a Shiner Bock (Texas pride intact), while Matt braved a Mad Elf, with a water on standby.

Our mystery stat game included estimates of holiday spending across the U.S. and Canada, and the motivation for today’s conversation: roughly 20% of Americans now work in jobs that didn’t exist 25 years ago. That stat, based on LinkedIn data cited by The Wall Street Journal, set the stage for our discussion on how the economy has evolved over the past 25 years.

It’s easy to spot the jobs that have emerged in recent years: prompt engineers, social media managers, app developers. Even long-standing institutions like universities now rely on roles in IT, marketing, and cybersecurity that simply didn’t exist 25 years ago. And beyond traditional workplaces, the gig economy has exploded, with Uber drivers, Instacart shoppers, and Grubhub couriers becoming a visible part of daily life.

But there’s a flip side: jobs that fade away. One of the clearest examples is video rental, where employment dropped from over 120,000 in 2000 to fewer than 13,000 by 2017. It’s a reminder that as technology and habits shift, entire industries can disappear.

Students often struggle with this dual reality. New tech can destroy some jobs while creating others we couldn’t have predicted. The fear that automation will leave everyone unemployed reflects a common economic mistake: the lump-of-labor fallacy, or the idea that there’s a fixed number of jobs to go around.

Labor market change can feel uncertain, even threatening. If 20% of today’s jobs didn’t exist a generation ago, what does that mean for the value of a college degree? For us, it reinforces the point: teaching students how to think, adapt, and collaborate may be the most reliable form of job security. Majors and tools will change, but curiosity, communication, and decision-making won’t be outdated anytime soon.

Cheers, and happy holidays!

This week’s pop culture references:

Jadrian brought a fun throwback clip from a 1994 episode of The Today Show, where the hosts puzzle over what the internet is and how email addresses work. It’s a great reminder of just how recent (and confusing) the digital age once felt.

Matt shared a scene from Sunset Boulevard’s “With One Look,” where a former silent film star (Norma Desmond) reflects on losing her place in Hollywood. It’s a striking example of creative destruction. New technology (talking pictures) can erase entire careers, even for once-iconic stars.
