It is not ridiculous. It is also the will of a democratic people. Maybe you aren't compatible with the American system as you seem to want some sort of classist system (let in more of the 'GOOD' people where you define who is 'GOOD'). We had that system before this one, and 'GOOD' was defined as western European. We decided we didn't like that system and decided that everyone should have a chance.
The US of A let Singaporeans in easily, but not South Africans or French. You let Chileans easily in but not Mongolians or Equadorians. You let Australians in easily but not New Zealanders or Albanians.
Explain how these exceptions are not "some sort of classist system" that favours some nations over many others?
Define how this was the "will of a democratic people"? Who got asked for these special country exceptions? Do the American people even know about this?
American immigration is utterly broken. I stand by that.
Nobody's here to argue that the system is fair or good. But I don’t think this particular carve out is classist. If it was like Monaco, Switzerland and Norway maybe you could argue that it’s favouring the wealthier upper class. Singapore and Chile are quite different nations economically though, they aren't really one individual distinct class.
