EU - US economies, why the US recovered.

What is the differences between Europe and US, why the economy is so sluggish in the old continent?

The key can be in the states policies. While most of the Europe have restrictive inmmigration policies, the US actually welcomed them legalizing 5 million illegals this year, now, European immigrants, when legalized become subjects of the welfare state, dependent subjets, like many Europeans, they rely on the state, and are scared of starting bussiness due to the increible expensive bureaucracy involved, while in the US, there is more freedom to do this, nothing to lose.
