I got an associates, bachelors and advanced degrees in the 70s. And I totally agree with you in respect to the limited extent that degrees are applicable in the real world, especially now. Someone can graduate with a computer science degree and their knowledge is obsolete on graduation.
I had some helpful classes, primarily in applied sciences and mathematics, subjects that don't really change. History classes have been helpful and writing courses as well, Most importantly, during the era I attended college, the emphasis was not so much on what to think as it was on how to think, how to find and process the information you needed.
One of the most successful people I ever contracted with told me he never went to college, he went to the Army. He said he had to train every college graduate he hired for his business, they didn't learn what he needed from them in college. His conclusion was that college is just a place you go to grow up, not a place that determines your success. College, military or a job with responsibilty after high school, he said the outcome could be the same.
