I see it both ways but these are all broad generalizations.
Yes, the lifestyle, to an extent, is great. Through traveling, I've grown to appreciate the convenience of certain things I loathe like Walmart.
I disagree with nearly every policy the current administration has and THAT is what I hate about America. In addition to the social problems that plague every society like poverty, racism, sexism, homophobia, etc.
The thing is, you have ignorant people across the board, no matter what country they live in or claim as their homeland. Some people in America think America's shit doesn't stink and as a "world power", we can pretty much do whatever the fuck we want and everyone else better
while some non-Americans who hate the American gov't and its policies, in turn, hate all Americans, think we all drive H2's, that we all have mansions and have no care in the world.
It all boils down to nationalism vs. stereotypes.
