One of the primary stated purposes of the bankruptcy bill was to cut down on abusive or fraudulent uses of the bankruptcy system. As Congressman F. James Sensenbrenner Jr. (R-Wis), one of the bill's key supporters in the House, argued, "This bill will help restore responsibility and integrity to the bankruptcy system by cracking down on fraudulent, abusive, and opportunistic bankruptcy claims." Opponents of the bill argued that claims of bankruptcy abuse and fraud were wildly overblown, and that the vast majority of bankruptcies were related to medical expenses and job losses. These arguments were bolstered by an in-depth study and survey of 1,771 bankruptcy cases by scholars at Harvard University, of whom 931 submitted to interviews. The study found that "about half" of bankruptcy filers in the year 2001 cited out-of-pocket medical bills in excess of $10,000 as a major contributor to bankruptcy (the average bankruptcy filer in this study was a 41-year-old woman with a median income of $25,000, slightly below the personal income average for that year).
