Morosky - Sending a little loving feeling in your direction.
ZD - Well, historically, our state education system has been largely determined by those situated closer to private than state education, with the counter-balance that they are answerable to an electorate who are largely place closer to the state system.
I'm not sure about the utilitarian argument, though - that it's in everyone's interest to have the best state system possible. Sadly, the fact that we don't have a really great state education system, or not universally great, anyway, suggests that, actually, it is either, on balance, "better" (as in, the greatest good for the greatest number") to have a cheaper, patchier system than a great, more expensive system or that it is, actually, "better" to have a system that implicitly produces a populace of very stratified educational outcomes.
I so get what you're saying, though. I, too, think that it would, actually, be better to have a great educational system.
