For everyone debating numbers, billionaires, millionaires, whatever. The absolute numbers are irrelevant, what matters is the wealth gap. If the absolute top of the wealth pyramid, 0.01%, earns more than the bottom 5% combined, it's a problem. A bigger ratio means more wealth concentration, or inequality, whichever term you prefer. The 1% controlling nearly half the wealth of any place, whether city, state or nation, should sound all alarms to do something ASAP to reduce the inequality.

Which never happens, because when you have that much money, you call the shots. Capitalism became a neofeudalism.
