Thomas Sowell said this quote

White liberals, instead of comparing what has happened to the black family since the liberal welfare state policies of the 1960s were put into practice, compare black families to white families and conclude that the higher rates of broken homes and unwed motherhood among blacks are due to “a legacy of slavery.” But why the large-scale disintegration of the black family should have begun a hundred years after slavery is left unexplained. Whatever the situation of the black family relative to the white family, in the past or the present, it is clear that broken homes were far more common among blacks at the end of the twentieth century than they were in the middle of that century or at the beginning of that century —even though blacks at the beginning of the twentieth century were just one generation out of slavery. The widespread and casual abandonment of their children, and of the women who bore them, by black fathers in the ghettos of the late twentieth century was in fact a painfully ironic contrast with what had happened in the immediate aftermath of slavery a hundred years earlier, when observers in the South reported desperate efforts of freed blacks to find family members who had been separated from them during the era of slavery.
