In lieu of the current student loan forgiveness program, forgive the student loans upfront by contractually obligating years of civil service. Some government positions require degrees; some require post-graduate education.
Those who choose to dedicate their lives to civil service should not be bogged down by student loan repayment while trying to make ends meet. Especially in lower paying jobs. Not only can there be the relief of financial pressure, but there can also be an increase in the quality of workers.
In the event that workers become former employees before they fulfill their obligation (by choice or not), require repayment in full. Also, penalize poor performance. Remove employees from the program who are just not cutting it.
