In 2016, nearly 28% of those with student loan debt did not earn a degree at all.
Well, I have to agree that going to college and assuming debt to do so doesn't make sense if one isn't committed to graduating. Matriculating to the workforce from college isn't hard to do, but it's nearly impossible to do, or do effectively (which includes graduating from a degree program), if one isn't committed to doing so.
The fact is that by the time one enters college, one is an adult. Colleges and universities are going to treat one as such, and part of that means they assume one is there because one wants to be and is committed to mastering all that's offered in the degree program and courses one selects.
If you or your kids are heading to college you had better have a plan.
I would say that it's more important that the person going to college have a plan, namely a goal achievement plan for completing their degree that includes what they intend to achieve and how they are going to achieve it. They also need to be ready and able to modify their achievement plan as it becomes apparent that it's necessary to do so.
Those actions are things they should have picked up, or that their parents guided them in developing, in the course of going to high school, so implementing any such plans should not be a challenge. If it is, they probably shouldn't be in college, at least not "right now." Going to college right after completing high school is not the best course of action, at that time, for all high school grads. As adults, it, again, is incumbent upon the individual to recognize that about themselves and act accordingly.
