You probably are strongly opinionated and people you meet are strongly biased subset of Europeans. I personally know no one that would want to live in US. Even the entrepreneurial types. They are aware about rampant litigation, exorbitant costs of even simplest medical procedures that is reflected in costs of health insurance and sheer volume of US tax code. I knew one person though, who went to US to buy some goods and smuggle them back without paying customs and VAT.
