The "female culture" has shifted more rapidly than the "male culture"; the image of the go-get 'em woman has yet to be fully matched by the image of the let's take-care-of-the-kids- together man. More important, over the last thirty years, men's underlying feelings about taking responsibility at home have changed much less than women's feelings have changed about forging some kind of identity at work.

Formerly, many men dominated women within marriage. Now, despite a much wider acceptance of women as workers, men dominate women anonymously outside the marriage. Patriarchy has not disappeared; it has changed form. In the old form, women were forced to obey an overbearing husband in the privacy of an unjust marriage. In the new form, the working single mother is economically abandoned by her former husband and ignored by a patriarchal society at large.

Three factors--the belief that child care is female work, the failure of ex-husbands to support their children, and higher male wages at work--have taken the economic rug from under that half of married women who divorce.

Here is a new car, a new iPhone. We buy. We discard. We buy again. In recent years, we've been doing it faster.

As motherhood as a "private enterprise" declines and more mothers rely on the work of lower-paid specialists, the value accorded the work of mothering (not the value of children) has declined for women, making it all the harder for men to take it up.

Even when couples share more equitably in the work at home, women do two-thirds of the daily jobs at home, like cooking and cleaning up--jobs that fix them into a rigid routine. Most women cook dinner and most men change the oil in the family car. But dinner needs to be prepared every evening around six o'clock, whereas the car oil needs to be changed every six months, any day around that time, any time that day.... Men thus have more control over when they make their contributions than women do.

Most women without children spend much more time than men on housework; with children, they devote more time to both housework andchild care. Just as there is a wage gap between men and women in the workplace, there is a "leisure gap" between them at home. Most women work one shift at the office or factory and a "second shift" at home.
