The reality: most of these students will not realize a return on the investment of their time and acquisition of a ton of debt that they cannot discharge in bankruptcy. Many will fail to attend class, fail to take notes, fail to do homework, fail to learn, and will not complete - but because they have already sunk huge costs into the endeavor, will continue incurring more costs in spite of the writing on the wall.
The economics means that these schools are unsustainable. However, some people find success through these schools. How can we continue to serve these people?
Perhaps we could avoid throwing the baby out with the bathwater by creating more community colleges, allowing more people to enroll in affordable community colleges, complete milestones at their own pace, while providing more direct subsidies of tuition for the truly needy. I agree that we would benefit from more German-style apprenticeship programs as well. For all of their worker protections, they still have incredibly low youth unemployment.
