jealousy is a curse, some people cannot accept when someone is doing better than them, and they do anything to stop them. There are too many people with 'that big chip on their shoulder' until they get rid of that, then they be a better person.
...everyone is as bad as each other on the island - locals and gringos...backstabbing, back biting, bitching.. you name it, it goes on and on and on. People are nice to you when they can get something from you, but once they know there no more left to get then they don't want to know you.
Jealousy, greed, selfishness, arrogance, self importance, self pity and the many excuses and lies, ...a place will never succeed on these things, it will just destroy itself. Unfortunately this is all the next generation can see, and so it will continue....yes sad but true
