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.
