The roles of husband and wife in the United States
have undergone significant change as the marriage system changed over
time.
Our image of the "traditional" American roles of husband and wife --
with
the husband being the breadwinner and the wife staying home and taking
care of house and children -- actually were not present for most of our
history.
By the end of the 19th century a majority of American
families were no longer living on family farms, and the Household
Production
System gave way to the Breadwinner System. The husband became the
breadwinner, and defined himself as a good husband and father primarily
on the basis of his ability to provide for his wife and children.
The wife found herself no longer in the labor force, but spending her
day
at home taking care of the house and children. However,
almost
from its inception, forces were at work that threatened the stability
of this arrangement between husband and wife.

The Breadwinner System works so long as both husband
and
wife can trust each other to keep up their side of the bargain.
If
the marriage ends the wife, with little or no experience in the work
force,
finds herself in a difficult situation. Look at the graph above
and
reflect on its significance for the Breadwinner System. Here are
some additional points to keep in mind:

Now the common marriage system in the United States is the Egalitarian System, one in which all the roles in marriage (provider role, socializer role, housekeeper role) are shared by husband and wife. With both husband and wife pursuing jobs outside the home, increasingly pursuing two full-time careers, there are some difficulties with this new marriage system -- especially when it comes to the raising of children.

Notice how as the century progresses, not only are more women working
but their work life is more and more assuming the male pattern.
In 1940 young women worked, but then permanently left the labor force
either when they got married or had children. Women during the
1950s - 1970s worked when they were young, left work to have children,
but then re-entered the work force when their children were
older. Their work life pattern assumed an "M" shape. By the
1980s there is no longer evidence of an "M" shape -- women enter the
labor force when young and then then did not exit when they had
children. Women from the 1980s onward have the same upside down
"U" shape pattern to their work life as males do. They enter the
labor force when finished with school and then work until they reach
retirement age.
