Perfect Competition Destroys Profits

Economics textbooks treat perfect competition as the ideal state: many undifferentiated firms, prices set by the market, easy entry and exit. Thiel flips it. In perfect competition, every firm sells a commodity, prices get bid down to marginal cost, and in the long run no company makes an economic profit at all.

That matters because capitalism is premised on the accumulation of capital. If competition eats every dollar of profit, there is nothing left to accumulate. Thiel's provocation: capitalism and competition are not synonyms, they are opposites.

The practical consequence is brutal. A restaurant in a crowded market fights daily for survival, squeezes wages, and cannot think past next month. It is not that competitive businesses are run by worse people. The structure of the market leaves them no slack.
