The paradox is that they’ll blame taxation for being broke even if the actual reason is capitalism.

I reckon one major reason is that taxation is the visible part of your money being “stolen” whereas capitalists profiting off your labour is… well, potentially visible if it’s a private company and the owner flaunts his wealth, but generally if it’s a big publicly traded company, or a foreign multinational, etc, you need to be looking at the annual reports or something, because there’s no real local boss taking all the profit.
