The lower the family income, the higher the probability that the mother must work. Today, 1 out of 5 of these working mothers has children under 3. Two out of 5 have children of school age. Among the remainder, about 50 percent have husbands who earn less than $5,000 a year-many of them much less. I believe they bear the heaviest burden of any group in our Nation. Where the mother is the sole support of the family, she often must face the hard choice of either accepting public assistance or taking a position at a pay rate which averages less than two-thirds of the pay rate for men.
