We live in an age where university level lectures and materials are available for free. Why are we paying a ton of money to obtain a limited slot that allows us to show up at a building for the same lectures and materials?
Is it personal attention? Almost certainly not, but even if it was that can be had on the open market for far less cost.
Access to specialized equipment? Well maybe, but surely there's a more efficient solution there.
Is it certification? Because in my experience, as well as that of many others, the degrees don't say much of anything about competence so what good are they? Besides, it's again a really expensive way to certify people and surely there must be a better method.
