The culture you were born into may very well be rotten, but don’t make the mistake of thinking that it’s the culture of “this landmass”. The USA is enormous, and contains a huge number of cultures and subcultures. I grew up here, too, and experienced nothing like what you describe.
Live the rest of your life abroad if you’d like, but don’t do so believing that everyone in the USA is from the same culture.
