I understand that your primary goal is avoiding economic competition with people vastly poorer than you, but lets not lose sight of the fact that the economy as a whole suffers when valuable work doesn't get done.
Actually, I am Romanian, I was in the US for 6 months on a J1 visa at a top company, and now I'm looking for a job in Europe since it's so difficult to emigrate to the US.
I just disagree with the principle that if you study philosophy, it's your fault that you can't get a job, whereas if you're a company and want to hire a software engineer for $70k and you can't find any, it's the government's fault, not your own. I would prefer to let the market do its thing.
Also, I think that if suddenly there would be only 100 visas per year allowed, companies would learn to deal with that, either by opening remote offices or being more remote-friendly.
In contrast, no one wants to hire the philosophy major. There is no one else to blame because no third party is preventing him from behind hired.
You aren't wrong. But one does wonder why technical professions must be maximally subjected to "competition with people poorer than them" while lawyers, doctors, teachers and government workers seem to exempt from such competition.
