An insane amount of money, world hegemony, and a very high standard of living. I’m not sure the average European appreciates just how comfortable life in the US is. And the average American doesn’t know that things they take fir granted are luxuries even to Western Europeans. Outside of a handful of small countries with specialized economies, European income per capita is at or below per capita income in even the poorest US state. Even the vast majority of poor people here have iPhones and cars and can afford to run their air conditioners at 68F all day.
