The problem is that people point to the problems of the USSR and say it’s because of communism, but when the USA does similar things, it’s just them fucking up, not because they’re capitalist. It’s a double standard hinted at by OP.

The problem with the USSR was not that they were communist. I think that communism worked well for them, which magnified both their successes (beating nazis, reducing poverty, increasing literacy, getting to space, etc), but also magnified their mistakes (suppressing religion, art, etc).
