If you trust Adam Smith, an efficient market would quickly make new goods and services available for the lowest possible price. People are supposed to be incentivised to sell things, and competition is supposed to stop an excessive amount of money being diverted to profits instead of reinvestment and price cuts. There are supposed to be systems in place that ensure that there are always opportunities for competition, but the wealthiest have the most power to erode those mechanisms and the most interest in eroding them, and neoliberals think an Ayne Rand novel is the definitive text on how capitalism works rather than Adam Smith’s work, so even if you land in the capitalism makes everyone better off mode, it doesn’t last for long before it falls back into fuedalism with extra steps mode.
