At the time, Supreme Court Justice Ruth Bader Ginsberg apparently thought it was about eugenics and population control . From the New York Times Magazine :
Q: If you were a lawyer again, what would you want to accomplish as a future feminist legal agenda?
JUSTICE GINSBURG: Reproductive choice has to be straightened out. There will never be a woman of means without choice anymore. That just seems to me so obvious. The states that had changed their abortion laws before Roe [to make abortion legal] are not going to change back. So we have a policy that affects only poor women, and it can never be otherwise, and I dont know why this hasnt been said more often.
Q: Are you talking about the distances women have to travel because in parts of the country, abortion is essentially unavailable, because there are so few doctors and clinics that do the procedure? And also, the lack of Medicaid for abortions for poor women?
JUSTICE GINSBURG: Yes, the ruling about that surprised me. [Harris v. McRaein 1980 the court upheld the Hyde Amendment, which forbids the use of Medicaid for abortions.] Frankly I had thought that at the time Roe was decided, there was concern about population growth and particularly growth in populations that we dont want to have too many of. So that Roe was going to be then set up for Medicaid funding for abortion. Which some people felt would risk coercing women into having abortions when they didnt really want them. But when the court decided McRae, the case came out the other way. And then I realized that my perception of it had been altogether wrong.
Margaret Sanger, the founder of Planned Parenthood, would have agreed .
