There is a big difference in value between different degrees in the real world. Yet the costs are similar. What someone studies is very important and universities do not do a good job of telling people that.

There is nothing wrong with art/music/history. If you are interested by all means take a lot of courses in them. You can learn a lot of valuable skills which is why good universities required a diverse background of "generals" that these (and many more) fit into. However they give far more degrees in these things than are needed. (even physics gets more degrees than the world needs - but most getting a physics degree can better pivot to something else well paying).
