Immigrants typically do well for a time, and later there growth levels out.
Now for the resident children, what call to discipline or even knowledge or even self esteem is there?
Especially if one has a poverty background.
After all, the State will keep you alive at a subsistence level, and if that is all you have known, why change?
Well you nailed tree key issues, poverty, welfare and ignorance. All of which I agree with, but none of which were the premise of your original comment.
the indians and chinese referred here are probably 3rd or later generations of immigrants...
