The authors who caused a stir with the theory that legalizing abortion led to a reduction in crime, are back and they're examining the effects of the Women's Lib Movement.
Their first book Freakonomics (despite the abortion theory) is a great read. There is a riveting chapter on the inner financial workings of criminal street gangs.
They're back with SuperFreakonomics where they take on ...uhh ohh.. Feminism. Every liberal in the world latched on to these guys and their abortion theory from the first book. Their credibility was impeccable. I wonder if those same libs will find them as credible this time around. I doubt it.
