Bankruptcy in many ways is a Christian concept.  American bankruptcy laws have Biblical roots.  The seven-year waiting period between personal bankruptcies that was the law until 2005, for example, is based upon Deuteronomy 15:1-2

At the end of every seven-year period you shall have a relaxation of debts, which shall be observed as follows. Every creditor shall relax his claim on what he has loaned his neighbor; he must not press his neighbor, his kinsman, because a relaxation in honor of the LORD has been proclaimed

and Leviticus 25, which describes the regulations both for a seventh year Sabbath and a fiftieth year of jubilee.
