Once again aquinas, simply because something is beneficial doesn't mean that it's the purpose of especially the federal and perhaps not even state or local government to provide. If your state or local government wants to provide for college funding, so be it, however, as I've mentioned numerous times, this isn't a purpose outlined in our Constitution or it's amendments. What isn't outlined the Constitution and it's amendments falls to the states and the people by direction of those same amendments.
Nobody is stopping anyone from contributing as MUCH as they want to the pursuit of their fellow citizens to gain a college degree, you're all free to sell everything you own and contribute it all and so am I. What I am not free to do is require you, by force if necessary, to fund another adult's college pursuit. With that in mind, how about you contribute what you deem appropriate to charitable and/or worth wile pursuit's and I'll do the same. In that way I'm not trying to put my priorities and preferences on you and you're not trying to put your priorities and preferences on me. Sounds quite equitable doesn't it?
