Of course, this has been known for very long. Moynihan was getting in trouble for saying it back in the 60s. It's also the reason why the Civil Rights Act includes women; a particularly angry racist congressman from Virginia added women to the bill (which was widely understood to be aimed at strengthening black fathers to keep families together) to get the whole thing killed (though some publications have argued that Smith was the Baptist rather than the bootlegger in the group that got women added to the bill). The bill was still destroyed by it, if not in the way originally pictured, since it passed.
