You missed the point.
First, black people in the US were not forced to stay in ghettos, and still aren't. I know too many people who never went (such as my family) and who left.
Asians had their "ghetto" period as well, remember.
Nor, we're discovering, does taking a person out of the hood take the hood out of the person..
It all boils down to culture. We had reasons our culture was dysfunctional, but those reasons no longer stand to keep us dysfunctional. We remain dysfunctional by choice.
ADOS were not forced to abandon marriage...we did that by choice, and only in the last 50 years.
ADOS were not forced to education as an aspiration...we did that by choice, and only in the last 50 years.
ADOS were not forced to abandon speaking standard English,...we did that by choice, and only in the last 50 years.
Those are cultural dysfunctions we chose, and those ADOS who refuse to practice them do well in America today.
