This is laughably untrue and, oddly enough, the part of this post that left me most bothered.
Whether that's a good way to spend 5 years - I don't know. But in practice it turned out that way.
I've seen countless arguments about higher edu and whenever somebody says that school didnt teach him x,y,z,
then people often try to counter it with something like
"ohh, uni's goal is to teach you how to learn and make aware of how big some domain is!
what you're talking about is trade school!" (it's terrible counter in my opinion)
