Capitalism is just a projection of our natural competition for scarce resources onto an economic system.
you could dekulak all 3500 billionaires, magically transmute their make believe money into hard cash, and that $20 trillion would yield less than $2500 per human. hooray?
But more important than the cash is the power that money buys. Defenestrating the uber-wealthy of their undue influence in society would have far reaching benefits beyond just money in people’s bank accounts.
