Alot of gang-bangers here. Are there people striving and succeeding? Yes.
My main point is people are people. Some smart, some not. Some good, some bad. And if we have a system in place that puts people in neighborhoods where they don't belong, i.e., they haven't reached the point where they can achieve that goal on their own, it is a recipe for disaster and resentment. Resentment when these immigrants destroy the property value of middle class people who have worked so hard to get where they are.
If they are going to have refugees come over here, I advocate classes that teach english and understanding American culture. When I say American culture, I mean very general things. Going by the little I know, it didn't seem like a good idea to drop the Hmong people off and not have them vaguely familar with their new home.
