"Wasn't much better than USSR" is such bullshit on so many levels that it's hard to even to begin. In the US:
- you didn't have quotas to write "correct literature"
- you wouldn't disappear in a gulag for 10 years
- you didn't have to worry about standing in a queue for 1-2h to get fresh bread and sausage (it's easier to contemplate stupid shit when you don't have to worry about food)
- you didn't get assigned to a specific workplace where you HAD to work
- the books you read didn't have ideological crap (due to quotas) like "and children stopped starving because country X is a part of a friendly USSR"
I skipped not relevant bits but probably I still missed quite a few because I can only relay what my parents and others told me (I was born in the late 80s so I didn't get to experience the full glory of USSR).
EDIT: I forgot to mention a well-known practice of labelling people physically ill[1], getting them into physical wards, and pumping them with drugs until they are no longer "a thread". There is no need for a trial, and you can be held there indefinitely.
