for that reason, having some level of education about all of that boring capitalist bullshit is definitely in an individual's self-interest, but only to ensure they can interact with it as little as possible. a truly free person would essentially never interact with capitalism at all, but true freedom is an abstraction and an ideal and something nobody can achieve.
the goal of a free individual should be to minimize the amount of time they waste on capitalism and maximize the amount of time they spent creating and enjoying art, reading, learning, debating, engaging in politics and whatnot.
so, when the issue is regime change in iran, that interests me. when the interest is the environment, that interests me. but when the issue shifts to finances and economics, i'd rather read about something else.
