I'm not saying immigration is good or bad, just that it's a symptom not a cause of an underlying issue.
Also, how many uber drivers have you met that are doctors, lawyers, engineers, etc waiting for their certification to be validated before they can work? It's anecdotal but I've met a lot of immigrants with professional degrees driving for uber because they can't work for months to years because they need to get recertified/authorized.

I'm no nameologist but I think it means they were a sailor who rode nukes around Oregon, like that one cowboy riding a nuke in that cold war documentary I watched.
Edit: here's a screenshot from the documentary
