3. I myself have never really cared too much about the cultural/racial aspects of PR statehood (aside from the languague and education issues). I am MOST CONCERNED with the fact that too much of the population is dependent on transfer payments and government employment for its livelihood.
As I have said several times, I believe that PR would be better off maintaining commonwealth status, and that American would be better off with independence. HOWEVER, if PR voted to become a state, I would welcome you with open arms, especially your sisters. ;-)
