The U.S. may be considered a racist hell hole, but just like everywhere else, it's really the few loudest ones that make a bad name for everyone else. On the whole, Americans are wonderful people living in a system that offers them a reasonably high standard of living for a reasonable work/life balance. They've got some issues, just like any country.
They've got a shit political system that just occasionally manages to be a beacon of light and hope to the rest of the world; a shit debacle of a medical industry that somehow has a couple of shining examples that manage to stand shoulder to shoulder with the best hospitals in the world; and an education system that fails about as many as it helps, yet still somehow manages to pull out a few of the best schools in the world. Quite how this is, I'm not sure.
Don't let stereotypes and bad press colour your perspective of a culture you don't know anything about. Visit, go attend some interviews, spend time to find places there you love. Spend time with people. Form your own opinions. You may be surprised.
As I live in Scotland I pay 40 percent tax on everything I earn over 41 thousand pounds.
I take it you went to the States ? Is it even possible for someone my age to get there to work?
