So is anticapitalism becoming mainstream in the USA? I would say yes, more or less: https://www.commondreams.org/news/2019/10/28/poll-sponsored-... Also, historically these ideas were pretty common in the USA, with anarchist IWW being the biggest union of its time.

And what you call "these insane ideas" is actually following articles the Universal Declaration of Human Rights as approved after the second World War. Do you consider basic human rights to be insane?

Also worth noting, most things are not "for free" in Europe. The little rights we have our ancestors fought hard for, and they are being dismantled as we speak in the name of neoliberalism. Not so long ago France had one of the best Education and Health systems of the world, but that ship has sailed because of the desire to privatize everything and sabotage public infrastructure in the name of private profit.
