> Much of the foundation of capitalism was based on flawed assumptions ("perfect information" being a major one)
Perfect information isn't part of the foundation of capitalism.
It's part of rational choice theory, which didn't exist until long ashtray capitalism. (There are arguments for capitalism rooted in rational choice theory, but those are retroactive justifications not the foundation of the system.)
> Huge amounts of abuse were allowed to be perpetuated as a resul
The abuse predates the theory “justifying” it, the theory isn't the cause of the abuse. Capitalism historically wasn't grounded in theory, it was grounded in the opportunism of the mercantile class under late feudalism leverage wealth, power, and the opportunities created by new technology to rearrange society so that the mercantile class (the subset that became the capitalist class) could displace the economic (and also political) power for the feudal nobility.
