As money dries up, some loans aren't going to happen. It is dangerous territory to consider reductions in student loans, but, there is a way to make the student loan money work more efficiently while not cutting off education to anyone--
Measure placement rates, and redline the bottom 5% of programs, by total students in school and major, so that entering freshman are told, before they pick a school and major, that federal loans will not be made available for that major, that year.
I realize some majors do not connect people to the job market directly. You would have "Placed into career", "placed into grad school", and "not placed".
Like history majors. Maybe it's easy to get a job with a history major from yale, but not some state school in Iowa. Well, someone with their heart set on working with history will see the placements rates, and notice that they can't get funding to go to Iowa anyway, can choose instead the school that will lead to gainful employment.
The beauty of this system is multifaceted-- once you redline a major, you cut off the supply of students: less students competing for the available jobs = more students get jobs = redlining self-corrects! Also, it might just help colleges serve students better.
Also, If the number of students in redlining programs declines as predicted, slowly more programs will be redlined and killed dynamically from year-to-year.
consider a ficticious would with 100 students per school, and 2 colleges with 10 majors, and 5 students in each major(50 students per each college). The you measure the placement rate and redline one program.
year one: baseline. 5 students each major, 50 students each school
year five: 1 major at School A redlined. School A's reputation declines. only 1 student enters the redline major. only 40 students choose school A, 60 flood school B. meanwhile, since 1% of the student body is not enough to get redlined, school B's weakest program earns the redline.
year three, the students are back to 50/50, as each school has one redlined program. Only 1 student enter each redlined program, 2% is not enough, so one more program gets redlined. meanhwhile, the supply of workers for the program redlined in year one has dried up, so it comes off the red list.
This of course was an oversimplification, and the real world system will have lag, but you get the picture. The students, and the loans, chase the jobs.
Now, I understand the college is about more than preparation for a job, and even engineers should be forced to take classic lit classes, blah blah blah. But the government's interests lie making loans where the chances of repayment are high, and, I daresay colleges can enrich and prepare people for jobs at the same time, and it's immoral to allow someone to aquire a debt that will be systematically difficult to repay in the name of "enrichment".
I am not sure how colleges will adjust when federal student loans are redlined. Maybe majors will get axed, maybe colleges will develop more sophisticated career placement assistence systems and alliances with local businesses, but I see all these things as positives. Because nearly all students depend on student loans, redlining a mere 5% should be enough to redirect students into majors with better chances of career placement.
There are, of course, many other ideas that can be implemented alongside this one. However those can be discussed on a different thread.
