Capitalism, which puts a price tag on everything rather than rewarding all workers with full access to the collective wealth in exchange for their hard work; and allowing a tiny handful of the population to become obscenely wealthy and powerful with a large chunk of the population becoming impoverished, results in extreme power imbalances that leads to... corporatism/fascism. If you want a system based on ruthless competition, can't pay/can't have, with a few controlling everything, you're going to end up with a fascist system.
