"that the Great Depression happens after the Roaring 20s. But stop for a minute and think to yourself, why should it? Why shouldn't the Roaring 20s have led to a 1930s that was the most pleasant period of economic history, at least for the West, to live in? There was a massive increase in technology. There was a massive increase in the construction of a physical capital, which is used to produce output. The 30s should have been incredible. I used to tell a story to my students. They're like, okay, imagine this. You're an alien who came to visit the Earth and you disguise yourself surgically to look like a human and you showed up here in the 20s. And you're like, wow, this is awesome. You know, all the drinking and dancing and partying. I'm gonna talk my friends into coming with me. So they go back to their home planet and they talk their friends into coming back in 1935. You're like, what the hell? You know, what's going on here?"
