Why do many people in the caribbean leave their islands?

Lots of people decide to leave their homes in the Caribbean islands and migrate to other countries, mostly USA and Canada, because of multiple factors. Some of them include:
- Corruption, in most of the islands is very wide spread, and also there's big influences by the mobs.
- Poor economy and very limited choices of workplaces.
- Weather conditions, because almost every year most of the islands suffer from hurricanes and have enormous losses economically, and there's lots of casualties.
