THOMAS SOWELL:  The inconvenient truth about ghetto communities’ social breakdown.

The “legacy of slavery” argument is not just an excuse for inexcusable behavior in the ghettos. In a larger sense, it is an evasion of responsibility for the disastrous consequences of the prevailing social vision of our times, and the political policies based on that vision, over the past half century. Anyone who is serious about evidence need only compare black communities as they evolved in the first 100 years after slavery with black communities as they evolved in the first 50 years after the explosive growth of the welfare state, beginning in the 1960s.

Yep.  Progressivism is all about keeping groups angry, alienated and feeling powerless for political profit.
