Look, I literally have a degree in economics from an Ivy league university, and I promise you I didn't come close to actually understanding any of it until many years after graduating -- by including the "it's all made up part."

Really, video games and thinking about video game design helped me get it. Because it's a design, and not something like science or nature. It's not that real or unexpected consequences don't happen -- of course they do. But it's exactly like what happens in game dev, because someone tweaks rules.
