Dupes graduate with a bachelor's degree, and believe their misfortune, lack of income, and debt problems can be alleviated by borrowing more money and pursuing a graduate degree as they contract more debt. This usually proves vain.
Since student loan debt cannot be discharged legally in bankruptcy proceedings, the only solution for many students is getting a scarce gov't job with a loan forgiveness option, joining the military, committing suicide, or emigration to a foreign country.
The rationale for guaranteed loans emanates from the notion that the state subsidizing the cost of education somehow makes it cheaper. In reality, making gov't loan guarantees and six-figure credit ceilings available to a demographic of mostly 18 to 25 year-olds, who have limited work and credit history distorts the marketplace. If colleges had to take that demographic as they were without the gov't subsidized loans, colleges would be compelled to control their costs, and be more affordable. Cost inflation of tuition prices is institutionalized at 5-6% per annum.
