Why didn't the writer mention the infamous work ethic of Puerto Ricans? That's 99.9% of the problem.
The majority of the residents of Puero Rico are functionally illiterate in one language and some in two.
There's always someone ready to tell us about the 50 residents of Puerto Rico that have died in the 3 years of the Iraq war, but they never mention the more than 50 that are murdered on their streets and the more than 50 others that are killed in traffic accidents EVERY MONTH IN PUERTO RICO.
At least the Puerto Rican members of our armed forces had a fighting chance to stay alive. You can't say that for the residents of Puerto Rico they left behind.
The violence inherent in Puerto Rican society is also an abject lesson in the failure of big government, Liberal/Socialist, fascist gun control and the lack of a death penalty for even the most heinous of crimes.
