(Note: A version of this episode originally ran in 2016.)

Back in 2016, things were pretty bad in Venezuela. Grocery stores didn’t have enough food. Hospitals didn’t have basic supplies, like gauze. Child mortality was spiking. Businesses were shuttering. It’s one of the epic economic collapses of our time. And it was totally avoidable.

Venezuela used to be a relatively rich country. It has just about all the economic advantages a country could ask for: Beautiful beaches and mountains ready for tourism, fertile land good for farming, an educated population, and oil, lots and lots of oil.

But during the boom years, the Venezuelan government made some choices that add up to an economic time bomb.

Today on the show, we have an economic horror story about a country that made all the wrong decisions with its oil money. It’s a window into the fundamental way that money works and how when you try to control it, you can lose everything.

Then, an update on Venezuela today. How it went from a downward spiral, to a tentative economic stabilization… amidst political upheaval.

This original episode is hosted by Robert Smith and Noel King. It was produced by Nick Fountain and Sally Helm. Today’s update was hosted by Amanda Aronczyk, produced by Sean Saldana, fact checked by Sierra Juarez, and engineered by Neal Rauch. Alex Goldmark is our Executive Producer.

“Wanna see a trick? Give us any topic and we can tie it back to the economy.”

That is the bold promise in Planet Money‘s tagline. And we believe the show does live up to it. Over the last year, we’ve told stories about breakdancing, rum, pagers, buffets, colors, and heartbreak.

But then one host wondered: what if we really held ourselves to that promise? What if we challenged ourselves to find economic meaning in the most esoteric and far-flung topics imaginable?

That’s when we turned to you, our listeners. And boy did you deliver. You sent in ideas so obscure, so banananas, so guaranteed to stump and bamboozle that our host maybe started to regret her life choices…but she was resolved to give it a try.

This episode was hosted by Sally Helm and Keith Romer. It was produced by James Sneed. It was edited by Molly Messick and fact-checked by Sierra Juarez. Engineering by Kwesi Lee. Alex Goldmark is Planet Money‘s executive producer.

Next week, JD Vance and Tim Walz will face off in the only confirmed vice presidential debate ahead of the election. As voters look ahead to what their economic policies might be, we look back to see what they have said and done, and how it turned out.

Planet Money’s newsletter author Greg Rosalsky has spent some time combing through the economic records of Vance and Walz, and has some knowledge to share. Why does Walz support universal free school lunches, and why do some criticize him for it? Why have some called Vance a “Khan-servative?” And, how much do these candidates represent a break from the past?

This episode was hosted by Nick Fountain and Greg Rosalsky. It was produced by James Sneed and Emma Peaslee. It was edited by Meg Cramer. Sierra Juarez fact-checked it, and it was engineered by Valentina Rodríguez Sánchez. Alex Goldmark is Planet Money‘s Executive Producer.

Table saws are extremely dangerous. The government estimates that injuries from table saws send something like 30,000 people to the emergency room every year. 3,000 of those end in amputations. The costs of those injuries are enormous. Are they also avoidable?

In 1999, inventor Steve Gass had a realization: Humans conduct electricity pretty well; Wood does not. Could he develop a saw that could tell the difference between the two?

Steve invented a saw that can detect a finger and stop the blade in milliseconds. Then, he tried to license it to the big tool companies. He thought it was a slam dunk proposition: It would dramatically reduce the injuries, and the cost of medical treatments and lost wages associated with them.

On today’s episode: What does it take to make table saws safer? When someone gets hurt by a power tool, there are tons of costs, tons of externalities. We all bear the cost of the injury, in some way. So, it can be in society’s best interest to minimize those costs. We follow Steve’s quest to save thousands of fingers. It brought him face-to-face with roomfuls of power tool company defense attorneys, made him the anti-hero of the woodworking world, and cost the lives of many, many hot dogs.
