"Puerto Ricans on the mainland have an illegitimacy rate over 50%. Go into any housing project in the Bronx "
The ones in the Bronx would be NewYoricans, not true Puerto Ricans. (At least that's how my true Puerto Rican mother-in-law refers to them.)
My impression of Puerto Rico is this: Cubans, Jews and Gringos own and run the best business, the Dominicans do all the shove work, the small educated native PRs go into politics, while the remainder of the island was dependent in some way on the US government. Its a sad situation indeed.
Again: while it is true that the natives deserve some of the blame for the situation, US government policy didn't help much either.
