You've obviously never worked in the ER of a large East Coast hospital.I have.For many years,in fact.I could tell you story..after story...after story...after story that would make the hair on your toes curl.
I grew up in New York City in a neighborhood that was heavily Puerto Rican. They had about the same number of good and bad people as any other economic-refugee immigrant group, and most the children of that generation have in any case moved to nicer places in the outer boroughs or the suburbs and assimilated so thoroughly that they’re undetectable.
I don’t see that they’re any different from Italians, Eastern European Jews (many of the early organized crime figures were from immigrant Eastern European Jewish families), Russians or any other economic-refugee immigrant group.
