Depends on whether you have lived in an advanced Western European country.
It also depends of your tolerance of rednecks, prudes, puritans, and ignorant people (which exist everywhere in the world, but have particularly large concentrations there).
Or on your tolerance of a messed up party system, a messed up legal system, a messed up prison system (and the biggest incarceration rates in the world), cops that have an open license to shoot people, and the worse and more widespread racism this side of South Africa. Or on your tolerance on very bad statistics on violence (especially gun violence).
Or on your tolerance for businesses having near feudal reign on their workers.
That said, if you have the money, and the connections, the US is a pretty good deal to spend them. Not to mention very nice landscapes, and generally good hearted and optimistic people (besides the aforementioned negatives).
Plus, for some industries (basically IT and movies), they're tops.
