I mean, yeah. The US has had its anti-Capitalist movements though. And the US is just beyond drowned in Capitalist propaganda and people are infamously un(der)educated as well. In my experience organizing, people go against their own interests out of ignorance and fear.

Either way, it is the Capitalist class manipulating the 'famous anti-capitalist US people', even if the latter falsely thinks it's in their own interest.
