Volunteer funding for libraries is a nice idea, but it's treating the symptoms instead of curing the illness.
What we really need to be doing is stopping people from gutting libraries. It boggles my mind that people who actively work to damage and destroy public education systems in deference to greed, religion, warfare, and the like aren't tried for crimes against humanity.
Some bored schmoe passes the time by smoking a joint (because fuck it, what else are they going to do - read a book from the shuttered library?), gets stopped by a cop and locked away in a cell for a decade or two. Meanwhile, the politicians pushing their insane personal agendas not only walk free, but live high on the hog, sleeping like a baby every night. Disgusting, ain't it?
