Puerto Rico also has had corruption problems that may or may not be linked to the classical problems of people appointing friends to positions, inefficient allocation of resources such that wealthier areas are better maintained and have more of the ear of the government when it comes to acquiring resources to keep things maintained. Nothing involving governments is ever totally perfect or fair so there will always be a situation where it is who you know that counts.
After Maria, the federal response to the destruction was inefficient and inadequate to restore things to their previous state. As you find in any disaster on the mainland, the cleanup operations failed to vet contractors to insure that those doing the work actually had experience managing a complex process like hurricane cleanup and as a result there was massive waste. That's become the normal condition for US post-disaster operations so this is not a knock on PR at all.
I would love to visit. I have read a lot about it. One day it might happen. Good luck to all who choose PR as their home.
