PR was doing ok ‘till they ran the US navy out. The loss of revenue from that decision must be in the billions by now.
On the upside, Vieques is an unspoiled paradise. Well, it’s full of Puerto Ricans, but that’s a necessary evil.
The Navy’s presence prevented development there.
I recommend a visit to Vieques, before it gets ruined. It is beautiful, but be prepared for the small hill on the runway; it’s unnerving.
