Dude I don’t think even the democrats would float this sort of plan. It’s one of those weird moments between planning the three stooges reich where he just glomms onto some idea that is actually super progressive without knowing it. Ultimately trump is apolitical personally I think—he acts based on narcissistic self interest, which is why it’s possible for weird shit like this to happen. He also just takes notes from whatever whackos are around that day, so you can be sure that any actual good or progressive ideas will get removed from the platform by one of the far right grifters he has in perpetual orbit, but still amusing to see.
The democrats would say they wanted to do this, then complain they’re not allowed to, and then produce a plan that provides green cards to foreign grads if they agree to live in an underserved neighborhood for 5 years, have a specific blood type, and complete a post-secondary degree within 5 years with the intention of working in green energy development after. Like some caveated-to-hell means tested crap that lets them say they tried, while effectively making it near-impossible.
