David Brooks points to an article on parents spending more time with their children. There's an education gap, i.e. before "1995, mothers spent on average 12 hours a week with their children. By 2007, that number had leapt to 21.2 for college-educated moms and 15.9 hours for those with less education." He asks:

I was fascinated by how parental time correlates to education. Is it possible that college-educated parents are spending more time passing down their advantages than other parents? Could it be that the rich replicate themselves by dint of hard work and parental attention, on top of all the other less worthy advantages?

Uncomfortable questions.

Gail Collins replies:

[T]here was lots of other interesting information in that article. One point was that the mothers get more time to spend with their children by doing less housework and cooking. However the fathers get it by spending less time at work.

I’ve read other studies that suggest the younger generation of well-trained professionals is less willing than their parents to devote endless hours to their careers they want a more balanced life when it comes to work, family and recreation. If that’s true the rich aren’t going to keep their hardest-worker honors for very long. And their poorer brethren can go back to feeling morally superior.
