In general, the economic returns to a college education have proved to be high. But for individual college graduates, the financial benefits are both variable and unpredictable. One important role of government is to provide some protection against those risks so that qualified citizens, regardless of wealth, can and will advance their education. Toward that end, well-designed student loan repayment policies should aim to ensure that borrowers with low post-college earnings do not face unmanageable payment expectations, and that those who are responsible and make manageable payments are not burdened with indefinite repayment obligations.
Such policies would help limit the risks of student loan debt for teachers, public health workers, members of the clergy, and others in lower paying but important jobs that require higher education, as well as borrowers faced with family medical crises and other unanticipated circumstances that contribute to unmanageable repayment burdens. However, the protections should not be so generous that they give borrowers an incentive to work less, earn less, or avoid repaying their loans.
