There is nothing a college can teach you that you cannot learn for free online. The social environment can be replicated for free. You're not paying six figures for an education, you're paying six figures for exactly two things:

1. Someone to write lesson plans for you

2. A piece of paper that tells the world you are capable of conforming with the sometimes-frustrating impositions of an institution for 4 years without making too much of a fuss in the process
