That might be a cheap bargain.
A bailout of PR's $120 billion (with a B) debt and pension liabilities would give every Puerto Rican over $35K.
Puerto Rico's population has declined 10% since 2005 -- that's 400K people who went somewhere.
And U.S. citizenship is probably what’s ruining the island - the 10% who left, imagine what they might have contributed to the island’s economy. Oh, actually, we don’t have to imagine - at the island’s per capita GDP of $25K, they would have earned $100B over the last 10 years. Maybe not enough to erase the debt, but enough to make a dent.
