Sorry to pop the bubble for you, it's plagued by inequality but compared to the rest of the world on average the USA is doing pretty damn good...
US is good depending how much money you have and what part of it you happen to be born in (what type of family) etc. Overall its very bad, you just don't see it.
A country could have shit GDP but have high quality of life. "Policy wonks judge programs by productivity, they want Americans to die rich, economists want Americans to die happy".
