Y'know, when you get right down to it, America's not all that bad a nation.
Sure, we're fat, ignorant, and stupid, but at least we're not starving, oppressed, or enslaved.
And, yeah, there are all those politicians who are corrupt, stupid, etc. Whatever, I can't even say I know anything that goes on in political circles anymore, since there's always another fact or something to weigh in before you can make "an informed opinion." Otherwise, you just make yourself look stupid.
We have a system which, true, might be based on human selfishness, but the fact that it acknowledges that selfishness makes us better for it, instead of trying to assume an ideal standard that would inevitably become corrupted.
All problems aside, though, there are very few other places on earth I would rather be living. Maybe Japan, but that's it.
