NY Times interview last year where Judge Ginsberg says, "Frankly I had thought that at the time Roe was decided, there was concern about population growth and particularly growth in populations that we don’t want to have too many of."

Q: Are you talking about …the lack of Medicaid for abortions for poor women?
JUSTICE GINSBURG: Yes, the ruling about that surprised me. [Harris v. McRae — in 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 don’t 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 didn’t 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.
