If anyone wants more info on the topic, John Oliver has a great, 13-min segment on U.S. territories along with the clearly-evil justifications for their situation. Wait till yall see the Supreme Court ruling. It should get way more attention in media discussions on this topic. His finale with America's Got Talent contestant is also an epic counter to that.
No relationship is one sided - it takes two to make it a relationship.
The US doesn't need Puerto Rico - Puerto Rico needs the US.
The US didn't “find” it, it took it by force.
EDIT: From another colonial power. I’m not sure Spain is really in the market for a Carribean colony right now, so it might not be that easy for the US to walk away and leave PR in its pre-US position.
That 1812 Constitution of Spain was a product of the Napoleonic wars and seems to have been basically ignored everywhere but Iberia-proper. So really, PR has never had proper representation to its colonial rulers. And technically PR has had a non-voting rep. in the US house of representatives since 1901.
Well, we do let them have one non-voting representative in the House (similar to D.C. and other territories.)
