So what more affects the prospects of an inner city boy growing up today in the same neighborhood Dr. Sowell did: Jim Crow laws of the South, or being taunted as "acting white" by his classmates? What more affects his brother, anti-miscegenation laws or the fact that his father is not part of his life?
If either of these boys succeed, they deserve a great deal of credit. If they fail, people shrug their shoulders and ask what more government can do to alleviate their suffering.
That is how we reached the soft bigotry of low expectations.
