If Europeans are more free to take chances, why is there substantially less innovation in Europe?
I don't think Europe is "worse" than the US. I think Europe is optimized for the poor whereas the US is optimized for the middle class and above. There are good arguments for both of these situations. In the US, it is widely felt that the system should serve the tax payers. Europeans, on the other hand, seem to have a lot more solidarity with the poor who, for whatever reason, don't pay significant taxes. Additionally (and controversially), I think a significant amount of the European attitude comes down to ethnic solidarity. European countries are ethnostates and the US isn't.
One interesting thing is that Europeans benefit from American innovation. They have iphones, windows pcs, use google, etc like everyone else.
