...You have to remember that there are seven and a half billion people on earth and only about fifteen hundred or so of them are billionaires. There's a kind of penumbra of rich people—another few hundred thousand—and a twilight zone of merely affluent people whose standard of living and location is basically the extent of their wealth, a kind of geopolitical fortune rather than a bankable one, and then basically everyone else is as poor as hell.
