I think if your earning potential is over 100,000 US dollars, you're better off in the United States than in Europe because the social safety net isn't required. By the time you have a job that pays 100K a year, it probably also has all the numerous benefits that European countries already provide: 401K matching for retirement, health, dental, and vision insurance, more generous paid vacations, etc. If anything, since you can buy all the social services or they are included in employment, you want lower taxes so you don't have to pay for everyone else (disregarding the philosophical/political implications of said taxes).
On the flip side, if you make less than 100K a year, European life is probably better. You're probably a person who wants a life and doesn't want to work 24/7. You get basic health care needs, the K-12 education and university systems are already paid for by your taxes. Since your earnings are relativley low to the top 1%, you are on the receiving end of the social safety net and the taxes directly help you.
