> basic general principle that men will do whatever is required in order to obtain sex, and perhaps not a great deal more. (One of us characterized this in a previous work as, ‘If women would stop sleeping with jerks, men would stop being jerks.’)

This makes it sound like it is just men who need sex and have to do things to get it. One would think that everybody needs sex and thus women need it too. And it would stand to reason that the less fortunate women would need sex and be not able to get it easily and thus have to resort to sleeping with jerks and raising kids as a single mother.

So just saying women should stop sleeping with jerks is not really a practical thing. If anything good men should be expected to sleep with not so fortunate women to cut the jerks out of the equation ;)

Kidding aside this is a very complex problem and the article trivializes it - education, assistance to kids in need(mental/physical health, financial, foster care), providing compatible opportunities and then setting expectations will make a dent in this problem. And then there are just incompatible people doing stupid things that should be left to their devices and outcomes - there is no fixing willful idiocy. But what social policies need to do is provide a way out for anyone who wants it.
