Edit: it does sound like they might get shorted on Medicare benefits? It's unclear.
Edit2: this article looks at the difference between spending and taxes, in 2011, for all states and Puerto Rico: https://www.economist.com/blogs/dailychart/2011/08/americas-...
If the poster was instead trying to use this bad connotation to assist the argument that Puerto Rico probably shouldn't be a territory (which I now assume after looking at your comment), then that argument was lost in what was written. The writing is unclear in its intent, and that is likely why some folks misunderstood it. It kinda assumes you get lucky and interpret what he's saying the right way.
Just wanna say that I completely agree, but also wanted to tack on their non-existent representation in Congress.
And the comment you replied to is also likely aware of such. That's why they pointed out a global cooperative body making noises about Puerto Rico and decolonization.
Also, your mention of Haiti is confused; it was a French colony, not a colony of the UK or US.
Nice catch. And yeah, I just wanted to try and make things clear - no intention to be sassy.
Morally, I don't think it matters in this case- whether it's a state or a territory or a sovereign government, the US (along with everyone else in a position to help) should be helping Puerto Rico as much as possible. It's just something I've never understood, and sadly it might be a factor in the current tragedy.
