What I see is that the Puerto Rican coming to the US are the young professionals, my wife have helped some of them to buy houses in the Raleigh NC Triangle area recently... Theses people are working in the medicine or technology industry, no in the landscape, construction or any other general labor - jobs,,, Some Americans in this camp are concern about the new competition.
In the other hand the ones moving to DR are the retired PR who are looking for a relaxing and inexpensive life as the man in the video stated.
US $ 1000. Dollars in DR is still good money!
