As a european i can say in the US there are very good restaurants!!! So the junk food story is a bit of a cliché.
It is a very difficult choice you have to make. Personally if you can reach the 350K a year, just stay in the US. (But how long would it take for you to reach that number???). Much less taxes to be paid and i believe if you have money, US can be a really nice place to live. Quality of life in general is better in Europe for common man. But as a pilot in Europe.....quality of life.....does that exist?
