Maybe they should have reduced expenses by going to a community college first, a cheaper college, lived at home, etc., like the taxpayers did whom you now want to pay your debt.
Or like my daughter, who enlisted in the Army, served 6 years, then used her GI Bill to pay for - first, Community College (AA Paramedicine), then BSN with grants and scholarships. All while working full time as an EMT. Now she's certified in both Emergency Medicine and CNOR.
