Pre-modernity. Sucks to be poor if you’re born into that world. China is the second-largest economy in the world, and the fastest growing. Liechtenstein's economy and its growth rate are a tiny fraction of China's. But if you had a choice between being an average resident of China or an average resident of Liechtenstein you'd be a fool to choose the former no matter what game theory tells you. What you choose to measure matters. A lot.
