I lived in PR for a few years. Almost everyone I met (thousands of people) had family in the mainland (and had been up there to visit them at least once). I was told that there were more Puerto Ricans on the mainland than in PR. I'm just imaging what would happen if everyone (or the majority) left PR to go live with their families in NY or Florida or wherever... for sure the debt would never get paid back since the tax base would be gone, the villages would quickly disappear as the fast growing plant life took things back over, the resorts would have to close unless they brought in a lot of Dominicans to fill the positions... it's crazy to think about, but I could totally see it happening.
