I think you need to do a little research about income equality, happiness indexes, and standards of living. America isn't bad but there are much better.
Also, I don't consume American culture and thought everyday. I live in the UK and happily read British newspapers (bearing in mind we've had printed news before America even existed), listen to European rooted music, drive a French car, and watch British TV and comedies. I think you'll find that American culture in America is so fucking Ameri-centrist that you don't realise that other cultures thrive happily in their native countries, we just don't feel the need to force them on each other.
And fucking lol at "for any real change to happen in our society it has to happen in America first", you haven't even got a nationalised health service. In lots of aspects, America is decades in the past and the conservative right wing nut cases will happily regress it even further if they can.
