eh... Germany, Netherlands, even France... Switzerland probably... all those places you'll have bright young hardworking people from Spain or Portugal or Tunisia moving there, getting tech jobs, and finding financial/material success. In many cases becoming citizens so their kids can have access to that life without jumping through a bunch of hoops for visas.

America is totally a place where a hardworking, intelligent immigrant can become fairly wealthy (assuming no catastrophic bad luck, ie. getting shot because the second amendment says that everyone should have a full-auto assault rifle), but it does not have a monopoly on that :)
