Lots of colleges have collapsed over the years, and lots of still-functioning colleges have closed down programs. Your degree will not magically lose its value if your college vanishes after you graduate. What will matter is the fact that you did complete your degree, and to a certain extent, where you completed it. You will even still be able to request copies of your transcript forever because those records will be transferred to another institution that will have the responsibility to maintain those records. When people learn that your college collapsed, the most likely response will be, “Gee that’s sad. That was a great place!”
Whether or not you should go to college now, or ever, is a whole different question. So put some thought to other ways to get the training you might need for a job you could be happy in. One of the happiest guys I know is a pilot on the Mississippi River. That career does not require a college education, or even a formal apprenticeship program. People who are interested get a job on a crew and work their way up with hands-on informal apprenticeships that help them prepare for the licansing exams.
