On any given night last year, half a million people in the United States were experiencing homelessness, and more than 60% of them were staying in emergency shelters or transitional housing programs. Now, those same facilities are hot spots for COVID-19. It’s hard to social distance when you’re cramped, sharing bedrooms and sharing locker-room style communal showers. Today, we’ll look back at the history of how America has sheltered unhoused people, and how those approaches can make it hard for them to get back on their feet even when there’s not a pandemic going on.

The COVID-19 pandemic arrived at a moment when the gap between rich and poor in this country had hit a record high. One place that inequality is most visible is in the neighborhoods where we live. Generations of discriminatory housing policy, and lending practices that favored white borrowers, have entrenched segregation in American cities. This week, we’ll examine the housing policies that emerged from past economic crises, policies that excluded black people and other people of color, preventing them from building the wealth that middle class white families built.

Millions of Americans who are out of work don’t receive unemployment benefits. That’s by design. Today, we’ll look at the history of the United States’ unemployment insurance system, how this country defines “unemployment,”and why the program was never intended to cover everyone who’s not working.

As long as there’s been such a thing as quarantine, each person’s experience under it has depended largely on their economic status. On this week’s show, we take a tour of quarantines through history, from the bubonic plague outbreaks in 14th and 17th century Italy, to the a typhoid outbreak in New York in the early 1900s and a few other stops along the way. Those quarantines looked very different if you were, say, an immigrant, or a Jewish textile merchant, or a sex worker.

Crises like the COVID-19 pandemic shine a spotlight on all the inequalities already lurking in the system, and ideas of what the government owes to people in quarantine have changed over the centuries too. Long gone are the days of the government sending your family fennel sausage, cheese and wine to make it through.

Chicken is America’s most popular meat. But chicken supply chains — in fact, many of our food supply chains — are in danger of breaking down. Part of the reason is the workers who process and package those goods are getting sick. In some cases, they’re dying.

For the first episode of our new season, “A History of Now,” we focused on America’s chicken supply chain because it raises a huge, looming question: How is it that essential workers don’t have essential protections? How do we get through a crisis — any crisis — if we can’t be sure our food-producing workforce is safe?

There’s not much more uncertain than our current moment. Our day-to-day lives and our economy have been upended by the coronavirus pandemic. On this season, “A History of Now,” we’re digging into the history and policies that help make sense of this current moment, a time where issues of wealth and poverty feel even more stark than usual. New episodes start May 13.

We just found the answer to a really big question that’s been bugging us for years, about why the opioid crisis has hit some places so hard while other places have been relatively protected. The answer comes in the form of new academic research, that builds upon our reporting. Specifically, a secret internal marketing document from Purdue Pharma that senior producer Caitlin Esch discovered in the bowels of a county court house. She’s on this bonus episode to talk about it.

On this day, 30 years ago, President George H.W. Bush gave his first address from the Oval Office. Bush held up a baggie of crack he said had been seized just outside the White House. Today, we’re revisiting our episode about that speech, the events that led up to it and the lives it affected. For more on America’s drug war, listen to season 3 of our show.

We’re hard at work on the next season of “The Uncertain Hour,” but in the meantime, we’re excited to share a new podcast from Marketplace: “This Is Uncomfortable.” It’s a storytelling podcast, all about life and how money messes with it. Every Thursday, host Reema Khrais will dig into the unanticipated ways money affects relationships, shapes identities and often defines what it means to be an adult. The first episode is out now. Subscribe wherever you get your podcasts.

Many people in Wise County agree that they can’t jail their way out of a drug epidemic, but there’s a lot less agreement on what to do instead. And we find out what happened to Joey Ballard.
