Not American, but here’s my 0.02 euros:

The strength of the country was always in its’ diversity and the fact that motivated people came together to build better lives.

Nowadays there are people who hate the former and in terms of the latter, immigration is pretty hard and the H-1B is a lottery that unfortunately favors sweatshops (and yes, I’m salty because I’m a software engineer with no formal education so y’all don’t want me).

I get that there are legitimate reasons for limiting migration (your own people do want to work too, of course), but it does also limit economic growth and influx of different cultures.

Being from a small country in the EU that nobody’s heard of, the EU and its’ open borders are sorta doing the same to us now: Don’t get me wrong, it’s still primarily other white people migrating here, but at least they’re people of slightly different cultures, with different experiences. It benefits everyone because we all have something to learn from one another.
