The Island of Puerto Rico is a cesspool of poverty and corruption. The Island Government of Puerto Rico is a cesspool of corruption. Nepotism, graft, and an under the table cash economy reigns. Their problems are their own. We can cut them loose and they may become another Haiti. (Their island neighbor to the North.) Alternatively, we can bail them out. There will be pressure on Congress from the hedge funds that bought Puerto Rican debt at distress sale prices. (The Puerto Rican Constitution mandates payment of the debt, but there is no money to pay it without drastic cuts elsewhere.)
We should not bail them out nor allow them Statehood (same thing) short of putting the Island Government in receivership, sending in the marines to maintain order, hordes of attorneys from the DOJ to prosecute, and repealing the Jones Act. Puerto Ricans are statutory citizens of the U.S. That status does not convey all the same rights as native born, or naturalized, U.S. Citizens. Their status can be revoked by Statute. The last thing we want to do is allow them Statehood without correction of the underlying problems that caused the crisis. It would be like adopting Haiti. (The Island of Puerto Rico itself has vast underused natural resources.)
Younger, educated Puerto Ricans are leaving the Island in droves, exacerbating the Island's problems.
