For every nineteenth-century middle-class family that protected its wife and child within the family circle, there was an Irish ora German girl scrubbing floors in that home, a Welsh boy mining coal to keep the home-baked goodies warm, a black girl doing the family laundry, a black mother and child picking cotton to be made into clothes for the family, and a Jewish or an Italian daughter in a sweatshop making "ladies" dresses or artificial flowers for the family to purchase.

The historical weight of gender inequality has tended to concentrate women in lower-paid jobs with fewer benefits, at the same time made them primarily responsible for care giving.

Extended families have never been the norm in America; the highest figure for extended-family households ever recorded in Americanhistory is 20 percent. Contrary to the popular myth that industrialization destroyed "traditional" extended families, this high point occurred between 1850 and 1885, during the most intensive period of early industrialization. Many of these extended families, and most "producing" families of the time, depended on the labor of children; they were held together by dire necessity and sometimes by brute force.

We urgently need a debate about the best ways of supporting families in modern America, without blinders that prevent us from seeing the full extent of dependence and interdependence in American life. As long as we pretend that only poor or abnormal families need outside assistance, we will shortchange poor families, overcompensate rich ones, and fail to come up with effective policies for helping families in the middle.

A two-parent family based on love and commitment can be a wonderful thing, but historically speaking the "two-parent paradigm" has left an extraordinary amount of room for economic inequality, violence and male dominance.

In industrial countries where male privilege is still firmly entrenched - in Spain, Italy, Japan, and South Korea, for example - women are delaying marriage longer than in America, and often resisting childbearing as well. They are less likely than American women to say that marriage is a good deal.

I think that divorce is a vital escape hatch for people stuck in marriage and it is not a sentence of doom either for adults or children. The community should develop better support systems for saving or restoring potentially healthy marriages.But we should also help people who decide to divorce have healthier partings.
