You are claiming a lot of absolutes in this. I attended college to expand my mind, learn new things, and mature into an adult. I went to a large but reasonably prices state school and did everything you said no one does. I don't even use my degree but going through thought me a lot of lessons I still use (working well with people I don't know, learning things quickly and applying them, making new friends). I, and I bet a lot of others, learned and grew a lot during University with out the notion of finding a career.
