if for no other reason then because US imposes on me a culture different from my own, while in USSR I at very least had the luxury of having my native culture being forced on myself
Isn't every country like that? There is a set of dominating values in every region, and a certain level of conformance to these levels is always expected. The question whether they are "native" and "non-native" is a secondary matter, as native values may not correspond with your point of view and can be more "binding" that those of another country. The only difference is that one tends to be more accustomed to their native values, and thus more forgiving in their evaluation, which is often clouded by nostalgia.
That said, as a citizen of a former Eastern Bloc country, I wouldn't choose neither my home country nor the US as my ideal place to live.
