Sorry for some of the random stats...it was a cut and paste.
The primary point is that government spending on education has outpaced inflationary costs, and provided no measurable improvement (that I'm aware of). Throwing money at something isn't always the best way to improve things...witness our healthcare. Why should there be any increase after inflation if it's not providing benefit? Is your comment about real wages not also non sequitur, or is there some link to educational expenses and value?
Again, I'm fine with increased expenses if they're used toward areas that have a demonstrable return in educational value.
