Not saying all troubles are related to a two class society but it can be a significant element. It's not just gangs it's a complex problem. Gangs result from disinfrancished groups, generally economic. It's all interrelated. Perhaps some reading on two class societies would be in order. During troubling times people and society's do un-rational things.

Don't see this behavior in St Bart's, Saba, BVIs And others. Only where there is an economically depressed population. Perhaps as part of the rebuilding there is a way to better integrate all and level the field. That benefits all.
