I did pretty well, but my career was in a field in which almost everything I needed and learned was via OJT. The degree was really pretty useless, except to get my foot in the door.

While the actual stuff you memorized may be useless, I've said for decades that what my college education taught me was how to approach a problem and solve it. Essentially, I learned how to learn.

To that end, I will never consider my degree "useless". YMMV
