I may be wrong on this, but was it the civil rights act debate that brought about the famous speech by Daniel Moynihan, regarding the destruction of the American family. It was one of the prescient speeches you can read.
I found it. It was not in the Act’s debates, but rather a report afterwards. The thesis of the paper was that without equal access the black family would continue to disintegrate and the single parent mother would be come the prominent family structure—leading to poorly educated and depended children. And the spiral would continue for generations. Sound familiar.
A link to the report from 1965 is here:
