We often hear that air travel is worse than it's ever been. Gone are the days when airplanes touted piano bars and meat carving stations — or even free meals. Instead we're crammed into tiny seats and fighting for overhead space.

How did we get here? Most of the inconveniences we think about when we fly can be traced back to the period of time just after the federal government deregulated the airlines.

When commercial air travel took off in the 1940s, the government regulated how many national airlines were allowed to exist, where they were allowed to fly, and how much they could charge for tickets. But the Airline Deregulation Act of 1978 swept all these restrictions aside – and stopped providing subsidies for the air carriers. Airlines had to compete on ticket prices. That competition led to a more bare-bones flying experience, but it also made air travel a lot more affordable.

In this episode, we trace the evolution of air travel over the past century to discover whether flying really is worse today — or if it's actually better than ever. We'll board a plane from the "golden age" of air travel, hear the history of one of the original budget airlines and meet feuding airline CEOs. Along the way, we'll see how economic forces have shaped the airline industry into what it is today, and what role we, as consumers, have played.

At the core of most of the electronics we use today are some very tiny, very powerful chips. Semiconductor chips. And they are mighty: they help power our phones, laptops, and cars. They enable advances in healthcare, military systems, transportation, and clean energy. And they're also critical for artificial intelligence, providing the hardware needed to train complex machine learning.

On today's episode, we're bringing you two stories from our daily show The Indicator, diving into the two most important semiconductor chip companies, which have transformed the industry over the past 40 years.

First, we trace NVIDIA's journey from making niche graphics cards for gaming to making the most advanced chips in the world — and briefly becoming the world's biggest company. Next, we see how the Taiwan Semiconductor Manufacturing Company's decision to manufacture chips for its competition instead of itself flipped the entire industry on its head, and moved the vast majority of the world's advanced chip production to Taiwan.

We wade into the heated debate over immigrants' impact on the labor market. When the number of workers in a city increases, does that take away jobs from the people who already live and work there? Does a surge of immigration hurt their wages?

The debate within the field of economics often centers on Nobel-prize winner David Card's ground-breaking paper, "The Impact of the Mariel Boatlift on the Miami Labor Market." Today on the show: the fight over that paper, and what it tells us about the debate over immigration.

(Note: A version of this episode originally ran in 2019.)

In 1794, George Washington decided to raise money for the federal government by taxing the rich. He did it by putting a tax on horse-drawn carriages.

The carriage tax could be considered the first federal wealth tax of the United States. It led to a huge fight over the power to tax in the U.S. Constitution, a fight that continues today.

When the vape brand Juul first hit the market back in 2015, e-cigarettes were in a kind of regulatory limbo. At the time, the rules that governed tobacco cigarettes did not explicitly apply to e-cigarettes. Then Juul blew up, fueled a public health crisis over teen vaping, and inspired a regulatory crackdown. But when the government finally stepped in to solve the problem of youth vaping, it may have actually made things worse.

Today's episode is a collaboration with the new podcast series "Backfired: the Vaping Wars." You can listen to the full series at audible.com/Backfired.

This episode was hosted by Alexi Horowitz-Ghazi and Leon Neyfakh. It was produced by Emma Peaslee and edited by Jess Jiang with help from Annie Brown. It was fact checked by Sofia Shchukina and engineered by Cena Loffredo. Alex Goldmark is Planet Money's executive producer.

We've lived amongst Elon Musk headlines for so long now that it's easy to forget just how much he sounds like a sci-fi character. He runs a space company and wants to colonize mars. He also runs a company that just implanted a computer chip into a human brain. And he believes there's a pretty high probability everything is a simulation and we are living inside of it.

But the latest Elon Musk headline-grabbing drama is less something out of sci-fi, and more something pulled from HBO's "Succession."

Elon Musk helped take Tesla from the brink of bankruptcy to one of the biggest companies in the world. And his compensation for that was an unprecedentedly large pay package that turned him into the richest person on Earth. But a judge made a decision about that pay package that set off a chain of events resulting in quite possibly the most expensive, highest stakes vote in publicly traded company history.

The ensuing battle over Musk's compensation is not just another wild Elon tale. It's a lesson in how to motivate the people running the biggest companies that – like it or not – are shaping our world. It's a classic economics problem with a very 2024 twist.

There's a behind the scenes industry that helps big brands decide questions like: How big should a bag of chips be? What's the right size for a bottle of shampoo? And yes, also: When should a company do a little shrinkflation?

From Cookie Monster to President Biden, everybody is complaining about shrinkflation these days. But when we asked the packaging and pricing experts, they told us that shrinkflation is just one move in a much larger, much weirder 4-D chess game.

The name of that game is "price pack architecture." This is the idea that you shouldn't just sell your product in one or two sizes. You should sell your product in a whole range of different sizes, at a whole range of different price points. Over the past 15 years, price pack architecture has completely changed how products are marketed and sold in the United States.

Today, we are going on a shopping cart ride-along with one of those price pack architects. She's going to pull back the curtain and show us why some products are getting larger while others are getting smaller, and tell us about the adorable little soda can that started it all.

By the end of the episode, you'll never look at a grocery store the same way again.

Graphite is sort of the one-hit wonder of minerals. And that hit? Pencils. Everyone loves to talk about pencils when it comes to graphite. If graphite were to perform a concert, they'd close out the show with "pencils," and everyone would clap and cheer. But true fans of graphite would be shouting out "batteries!" Because graphite is a key ingredient in another important thing that we all use in our everyday lives: lithium ion batteries.

Almost all of the battery-ready graphite in the world comes from one place: China. That's actually true of lots of the materials that go into batteries, like processed lithium and processed cobalt. Which is why it was such a big deal when, earlier this year, President Biden announced a tariff package that will make a bunch of Chinese imports more expensive. Included in this package are some tariffs on Chinese graphite. He wants to create a new battery future—one that doesn't rely so much on China.

In this episode, we get down on the ground to look at this big supply chain story through the lens of one critical mineral. And we visit a small town that realizes that it might be the perfect place to create an American graphite industry. And we find that declaring a new battery future is one thing, but making it happen is another thing entirely.

Most economic textbooks will tell you that there can be real dangers in running up a big national debt. A major concern is how the debt you add now could slow down economic growth in the future. Economists have not been able to nail down how much debt a country can safely take on. But they have tried.

Back in 2010, two economists took a look at 20 countries over the course of decades, and sometimes centuries, and came back with a number. Their analysis suggested that economic growth slowed significantly once national debt passed 90% of annual GDP... and that is when the fight over debt and growth really took off.

On today's episode: a deep dive on what we know, and what we don't know, about when exactly national debt becomes a problem. We will also try to figure out how worried we should be about the United States' current debt total of 26 trillion dollars.

For thousands of years, getting light was a huge hassle. You had to make candles from scratch. This is not as romantic as it sounds. You had to get a cow, raise the cow, feed the cow, kill the cow, get the fat out of the cow, cook the fat, dip wicks into the fat. All that--for not very much light. Now, if we want to light a whole room, we just flip a switch.

The history of light explains why the world today is the way it is. It explains why we aren't all subsistence farmers, and why we can afford to have artists and massage therapists and plumbers. (And, yes, people who make podcasts about the history of light.) The history of light is the history of economic growth--of things getting faster, cheaper, and more efficient.

On today's show: How we got from dim little candles made out of cow fat, to as much light as we want at the flick of a switch.

Today's show was hosted by Jacob Goldstein and David Kestenbaum. It was originally produced by Caitlin Kenney and Damiano Marchetti. Today's rerun was produced by James Sneed, and edited by Jenny Lawton. It was fact-checked by Sierra Juarez. Engineering by Valentina Rodríguez Sánchez.
