(1) Men and women experienced the Great Depression differently, partly because of the gender roles that governed male and
female behavior in the 1930s. (2) From childhood men had been trained to be breadwinners; they considered themselves failures
if they could no longer support their families. (3) But while millions of men lost their jobs during the Depression, few of the
nation's 28 million female homemakers lost their positions in the home. (4) In contrast to men, women's sense of self-
importance increased as they struggled to keep their families afloat.
