Margaret Sanger laid the groundwork for China's one child policy

You can readily feel Margaret Sanger's contempt for the poor in the words of this speech the founder of Planned Parenthood gave at Carnegie Hall in 1922:

China, the mysterious fountainhead of art, philosophy and the deepest wisdom of the world, has been brought down by the breeding and multiplication of the worst elements of the yellow race.

Here are masses of humans who live below the level of animals. They eat, sleep, and breed in the crowded streets and sunless alleys. Go through the reeking labyrinth of one of these native Chinese cities. Go on a day when a hot sun brings out all of these wretched incurably diseased specimens of what we dignify by the name of human.
