So tell us, then, how Vietnamese immigrants, moving here with literally just the shirts on their backs, moved into the same neighborhoods and sent their kids to the same schools, and have lifted themselves and their kids out of those neighborhoods and into the middle class and to college, to where they no longer need welfare?
It's not that no one is addressing your 'thesis' - it's just that most folks recognize it for the nonsense that it is.
In my experience, you can say the same thing about (recent) immigrants from Africa.
Sorry. Not into what most folks think. Some folks here think differently. Noticed that have you?
