Yeah, this. I know it's tempting to imagine that all the people opposing good policies are evil masterminds operating on a reverse Marxist understanding of the world, but the problems are much more structural. All sorts of weirdos run for office, and businesses fund the campaigns of the ones whose weirdo ideas line up with what they want, and that is sufficient to put people in power who perpetuate capitalist interests, without anybody actually thinking "perpetuate capitalist interests" at any point in the process.
