The correct answer to this open question is the following.
The standard of living of Jamaica, in the Caribbean, is so different compared to that in the United States. Jamaica is a poor, underdeveloped country that has so many economic and politic problems. The public infrastructure is limited, the level of education is not as advanced as in the US, and the creation of jobs is short. Oftentimes, Jamaican people have to migrate to other countries in order to find better living conditions.
