Imagine borrowing money to attend an expensive top level college for 4 years, then borrowing money to attend 4 years of medical school, then several years at moderate income as an intern and resident, then trying to pay off those loans with a spouse and children and a mortgage and a car loan with a $156,000 income at age 30 or more. Very tough indeed.
