Cloward-Piven
Largely, but with a liberal sprinkling of Saul Alinsky and George Soros thrown in.
Also flying under the radar has been a concerted drive to sign up young minority groups to SS disability benefits. I have seen it in two Texas cities, one large (Dallas) and the other small (Georgetown). Overflowing waiting rooms and long lines outside for days and days. Each minority applicant was accompanied by an adult minority "counselor" with briefcases and folders in hand.
