This is kind of my point (and, I assume, the OP's): most of those people move to the city to become millionaires, not because they already are millionaires and prefer to live in the city. In that regard, cities do sort of spontaneously generate millionaires in that most wealth is produced there and not (there's probably a better way to phrase this) imported.
