The thing is, both USSR/China and USA don’t fit the ideals of Communism.

Just because you get rid of economical suppression doesn’t mean you can’t have political suppression. Sure these countries had economical problems but a lot of their problems could have been avoided if the government would have actually worked for the people and not for themselves.
