Why do you think your experience allows you to make a general conclusion? There are at least a few universities which teach truly valuable things: work ethic, overcoming difficult problems, and using practical (and modern) tools.
The reason I allow myself to make my claim as such is due to a combination of things, including personal experience: experience of friends and family (intelligent people with excellent marks in popular fields, unemployed or barely getting by), $1 trillion plus debt that doesn't seem to be going away anytime soon (you'd think that students receiving a good education would be able to land good jobs to help them pay their bills), and albeit anecdotal, Ivy League students who are singing in the rain.
Which universities are you referencing? And more specifically, are they state or public universities that the average family can afford to send their child to?
Despite a narrow scope, I thoroughly believe that universities in general have evolved into a means for subduing the general public. It's an immaculately designed mouse trap that masquerades as a positive future. A great parallel would be diet pills. Just pay three installments of 49.99 and you'll be thin (read: drowning in employment opportunities) in no time.
