a 1969 memo written by Frederick S. Jaffe has been a source of controversy. The memo, written to Berelson while he was head of the Population Council, included a table that summarized many proposals from various sources regarding population control. .... "The report was prepared in behalf of Planned Parenthood's Population Education Staff Committee as a basis for discussion of and action on the U.S. population problem by the Planned Parenthood national organization."
Furthermore, just two years later, Berelson and Jaffe would work together on the 1972 Rockefeller Commission Report. Many of the ideas discussed in the memorandum were incorporated into the Rockefeller Report.

Tells you everything you need to know: the Rockefellers have a LOT to answer for.
