I remember the first time I interviewed a relatively unknown economist named Nouriel Roubini. It was 2005, and as we sat in his New York University office, he laid out his scary vision of the future. Roubini is a specialist in the flow of money around the world and the crises that (sometimes) result. But on that day he wanted to talk about the U.S. housing market.

Homeowners, he said, had become too used to financing their lifestyles with money siphoned from overvalued homes. This housing bubble would pop, he warned, and send the world into a vicious recession, possibly even a depression. I remember leaving his office both stunned and confused. Only after calling a few leading economists was I reassured that this Roubini guy was expressing a fringe view that merited little attention. Like a lot of reporters that year, I turned around a tongue-in-cheek story about Dr. Doom and his scary (but probably best ignored) world view. Oops!

A few years later, I interviewed Richard Wolff, who is probably America’s most prominent Marxist economist (though it’s not a hugely competitive field). Wolff also walked me through his view of the next few years. He explained that the puncturing of the housing bubble, then apparent, would lead to a crisis much deeper than anyone understood: it would fracture American confidence in capitalism; the economy would stay stalled for a long time; and there would be global chaos. This time, I didn’t even bother calling other economists to check out Wolff’s story. The guy was a Marxist! Days later, Lehman Brothers collapsed.

Once the crisis hit, it became popular to scour the past for apocalyptic predictions that had come true. While many gloomy forecasts came from the left — notably Paul Krugman and Dean Baker — there was one particularly prescient voice from the right. As early as 2004, Peter Schiff, a libertarian investor, was arguing that the housing-fueled economic boom was a bubble waiting to burst.
