Sounds like there's still a fine crop of young nitwits ready for harvest - if you're the grim reaper. Feminism has imbued these young women with a seriously dangerous sense of equality with men in all realm - including the physical. Coupled with the bogus fatalism of today's cynical hipness, a psycho ought to be able to cut a wide swath before his own pathology and blindside caught up with him.
While it might be easy to target feminism, that is like Hefner taking credit for the sexual revoultuion...the real answer is THE PILL. If you feel safe from lifes biggest consequence then you take risks. Ask any man what changed in the 60s and it wasn't pot or "free love" it was the pill. Top that off with the free ride parents give their kids and nobody thinks they will ever be off the gravy train and face the music.
