Higher Education of course should be free and not associated in any way with whatever commercial gains might be connected to it. The provision of Higher Education represents any governments 'faith' in it's populace. Maybe they (youth) will (produce loads of money) maybe not (realize something else has to be done and take to the streets) It's as simple as that, but you should give all the opportunity to engage in the educational process as far as they are able to find out their options.
I support the student actions today. I am also hardly surprised by the violence which is vastly dramatized by the 'media' as 'mock shock!' Any reading of Badiou for instance, would illustrate the ridiculous rejection of historical fact that such whimpering represents. A few broken windows are nothing.
