Go and read the Soviet Constitution of 1936 (Stalin) [1]. It talks about freedom of speech, freedom of press, assembly, demonstrations. It actually goes much further than the US constitution. It talks about the right to rest and leisure. Old age care. Education.
We all know that the reality of life under Stalin didn't quite live up to this. A constitution is just a piece of paper. It doesn't mean anything unless it is enforced. That's why I think we focus too much on things like originalism vs living constitution... the reality is that we should be focused on maintaining our democratic institutions which no longer look as secure as they used to.
