DonDiego apologizes. He neglected to include the GAO Report reference: Federal Student Loans.
Here's the initial summary of the GAO opinion of Education Department estimates of the costs of the IDR Student Loans:
"For the fiscal year 2017 budget, the U.S. Department of Education (Education) estimates that all federally issued Direct Loans in Income-Driven Repayment (IDR) plans will have government costs of $74 billion, higher than previous budget estimates. IDR plans are designed to help ease student debt burden by setting loan payments as a percentage of borrower income, extending repayment periods from the standard 10 years to up to 25 years, and forgiving remaining balances at the end of that period. While actual costs cannot be known until borrowers repay their loans,
GAO found that current IDR plan budget estimates are more than double what was originally expected for loans made in fiscal years 2009 through 2016. (the only years for which original estimates are available). This growth is largely due to the rising volume of loans in IDR plans."
boldface added - DD
i.e. The Education Department methodology systematically under-estimated the costs of "forgiving" the loans.
The majority of the GAO report is a discussion of the inadequacies of the Department of Education estimates.
Nonetheless, one of the Charts demonstrates just what The Obama could accomplish with his "pen and phone". The Obama dramatically increases the availability of IDR loans with his pen in 2010. Loan applications immediately skyrocketed. Somehow folks can recognize a great giveaway when The Obama offers it !
