It totally depends on the program and degree in my opinion
Many of the liberal arts degree for example I believe are bad for the country (gender,racial , religious studies for example ).
Me taking RELS 3755 On the Divine was bad for the country!? Gimme an effing break.
How much did you end up paying for the privilege of taking that course? The major reason to learn the liberal arts via a college education instead of self study is so that it can be part of your credentials. That's even true for quite a few STEM courses. Beyond getting a credential, the only other thing gained from the collegiate setting academically is that you are in theory following a curated syllabus of courses that ensures you have a comprehensive view of your chosen field of study. Back in the 12th century, if you wanted access to knowledge you had to go to where the knowledgeable people were, namely a university. But this ain't the 12th century, it's the 21st. There's zero need for colleges as places to learn. They're places to gain a credential that shows that you have learned.
