Embattled MIT professor Jonathan Gruber has not only gotten in trouble for bragging about helping President Obama put one over on the American people with Obamacare, he’s also been uncovered as an abortion advocate–but not a run-of-the-mill advocate of “women’s rights.”

No, Gruber’s abortion advocacy is of a particularly pungent eugenics variety. He’s on record repeatedly making the case from social science that abortion is a “social good” because it reduces the number of “marginal children,” by which he means urban poor–those he says can be counted on to commit crimes if they were ever born.

Gruber co-authored a paper during the Clinton years which argued that legal abortion had saved the U.S. taxpayer upwards of $14 billion in welfare benefits and that it also lowered crime.

Gruber’s work heavily influenced other researchers, including a paper called The Impact of Legalized Abortion by Steven Levitt of the University of Chicago, whose later book Freakonomics and whose ongoing work makes the strongest case that abortion legalizations in the 1970s caused a dramatic drop in crime twenty years later.

Pro-lifers have always wondered why the black community has not responded more aggressively to the fact that so many abortion clinics are located in poor neighborhoods and why the black abortion rate is so much higher than whites.

A documentary called Maafa 21 argues that abortion is a part of what they called a “black genocide.”

African-American marketing expert Ryan Scott Bomberger founded an organization called The Radiance Foundation that makes commercials for the unborn child with a special emphasis on the high incidence of black abortion. Emmy-wining Bomberger’s toomanyaborted.com campaign looks specifically at black abortion. One meme calls abortion a “civil wrong” and that blacks are “still not free at last” because of abortion. Bomberger is being sued by the NAACP for calling the group “pro-abortion.”

A group called 41 Percent tracks all abortions in New York City, which has an abortion rate at twice the national average, points out that the abortion rate in the largely black borough of The Bronx is an astounding 47%.

These are the types of communities Gruber meant when he referred the “marginal children” who were the most likely to end up on welfare and committing crimes if they were allowed to be born.
