I think it’s pretty hilarious that you assume everybody opposed to capitalism is Russian, and use that as a counter-example for why “communism” is failing today.
Did history stop for you in 1991 or something? The neoliberals won; Russia has been a hyper-capitalist abomination living in the corpse of the USSR for over three decades now. Why would we care that Russia sucks? Everybody knows it sucks now.
