The lifestyle is a contrast in perceptions.
Most of the locals who have never been off the island believe that everyone living in Canada and United States are rich.
This is because of two factors, the first is the tourists they see spend money like water and second is, returning locals want to impress all their friends as to how successful they are.

The contrasting mistake made by the tourists is not appreciating that the average worker makes less than $200US per month. Cars, clothes, shoes, radios, televisions and even food costs more than in the States. The only thing that maybe cheaper is housing and that could be debated as most tourists would not be content to live in such small homes.
Don't be fooled by thinking they they are poor though, you can't compare the quality of their lifestyle with yours, they live in the country that most tourists work all year just to spend two weeks holiday there.
