If you want to argue that college is about human capital creation rather than signalling, be my guest. But insofar as college is signalling, it directly redistributes wealth from those without the signal to those with it.
Interesting link but you seem to be missing the point.
I agree there may be an argument to be made that in cases, under certain circumstances, provided you can measure certain variables, the best action that results the "most public good" would be reducing university funding. If that's what you want to argue, then you'll need to do the legwork of gathering data that supports this conclusion.
The OP has not done that and is not even attempting to do so. He's made some overly simplistic arguments against university funding that are utterly lacking in depth.
EDIT: Can the downvoters please explain themselves?
Yes it does. Please learn about signalling.
