Personally, I think it’s part of the petty-bourgeois delusion that a person can become part of the capitalist elite instead of realizing that they have more in common with the working class.
False Consciousness. Some people clearly see the problems with capitalism and blame the Jews, some immigrants (and many both), and some people really believe the things they were taught in econ 101 and wind up blaming the problems of capitalism on not enough capitalism.
I think libertarianism as we see it in the US is a uniquely American phenomenon (which occasionally gets exported abroad like in Argentina) that’s born out of our quasi-religious worship of the constitution and the founding fathers. Every US child is taught in school that the founders were all once in a generation geniuses and that the constitution is a masterwork of politics and not a badly outdated document that is only ever invoked by the ruling class to consolidate their own power. The founders believed that capitalist markets were a force for liberation, so we get taught that in high school - although ironically the modern version of that idea of a completely unfettered market is not at all what the American founders had in mind, it’s the extreme that you get to by following their logic.
