CAPITALISM FAN: See, the problem with setting 'fair prices' for goods is that you create shortages! But if you just let THE MARKET (TM) set the prices, there are no shortages ever!
THE MARKET (TM): Hi so we raised the cost of houses to ONE MILLION DOLLARS. And we didn't build any new ones because that would lower the price. Literally fewer people can now live in houses.
CAPITALISM FAN: That's not a shortage. Shortages are what affect millionaires, not morally bad poor people who eat avocados.
