I would argue against the statement that all 'truly high talented people' (whatever that may mean) will leave Europe because the salaries are too low. At least in Academia I know plenty of smart people happily working away in Europe. I suppose it may well be different outside of academia, but not every (smart/talented) person in the world has a high salary as their #1 priority. To me, and to many of my friends/acquaintances, quality of life is also extremely important. I would rather, in the long term, live in a economically and politically stable country with good public (health) services and receive mediocre payment, than to receive high payment but with poor quality of life.
You can get good quality of life in US even without a monstruous salary, and political situation is not really worse than what is happening in Europe...
