The Two-Income Trap - Elizabeth Warren [122]
28 For a tabulation of Justin and Kimberly’s predivorce expenditures, see “Typical budget, four-person family” for “Justin and Kimberly” in note 121, chapter 2. As in the 1970s example, child support is calculated at 18 percent of the ex-husband’s income. The calculation assumes that Kimberly keeps one car and Justin takes the other. It also assumes that Kimberly keeps the same, predivorce expenses for the mortgage, health insurance, and child care. We note that one-quarter of noncustodial parents provide health insurance for their children. Timothy Grall, U.S. Department of Commerce, U.S. Census Bureau, “Child Support for Custodial Mothers and Fathers” (October 2000), p. 5. If we assumed instead that the father provides health insurance for his ex-wife and his children, the family’s discretionary income would decline slightly less precipitously after divorce. Under this scenario, postdivorce discretionary income as a proportion of predivorce income would be 21 percent in 1973 and 6 percent in 2000—an improvement of 2 percentage points in both years.
29 In 1977 only 38 percent of families had a bank-type credit card, compared with 68 percent in 1998. Thomas A.

Credit card debt calculated as revolving credit per adult divided by income per adult. The earliest year in which consistent data on both credit card debt and savings rates are available is 1981. We note, however, that by beginning in 1981, we understate the magnitude of the change over the past generation. In the early 1970s, credit card debt for the average family was even lower. In 1968, for example, total revolving credit outstanding was just $2 billion, compared with $626 billion in 2000. Durkin, “Credit Cards,” p. 623.
