Most Americans wouldn't be eligible for a resident visa to move to most European countries (and vice-versa); and when they would the process is long and expensive. I don't know why people from the US often, even knowing about their own country's strict immigration requirements, assume that they themselves can just pick up and move to any country they want (e.g. Europe, Canada, Australia, etc). 9/10s of the US population aren't in high demand jobs, most countries don't want you.
