aside from it being trendy to say equality and espouse those values, what about PR’s status suggests the residents would be anything other than a 2nd class of citizen under the United States?
That would create additional outcomes to PR that they are never asked about
The insular cases are pretty unrecognizably appallingly racist for what we expect of the court, really go read them, so I could see them overruling it and wind up dropping Puerto Rico and Congress being unable to reach consensus on any other outcome
Puerto Rican's would gain some things in medicaid, have to pay different rates of tax, and lose some status in UN and LAC community contexts.
On the mainland, both major parties ostensibly support in principle self determination. That said, I don't see how the current political landscape could produce it, given the fracture lines.
I loved this footnote in the wiki page:
Another misconception is that the import/export taxes collected by the U.S. on products manufactured in Puerto Rico are all returned to the Puerto Rico Treasury. This is not the case. Such import/export taxes are returned only for rum products, and even then the U.S. Treasury keeps a portion of those taxes
Now it's an authoritarian country where everyone but Americans go to party.
