I work in a major tech company and never check email outside work hours, which I cap at 40 hours a week. I never work weekends, never check work during weekends or vacations.
I make much more than my European peers, have a better car, better weather and bigger house. I have 25 days of paid vacation. While this is better than the US average, I don't know a single person in my friends group wanting to trade the US for Europe, including my Europe-born friends.
