Its an issue fraught with peril. Puerto Rico has no statehood, so they're a lesser property within the US as a whole. They have very little economy besides tourism to speak of, enormous amounts of corruption through the various governmental levels, and a populace that is rapidly aging. They plugged budget wholes with debt until it reached levels requiring an independent oversight board stepping in to take over. If you're able to find work on the mainland, you bounce, and only stick around on the island if you can't.
I'm not sure what the solution is. You can't write blank checks to a broken government forever.
