The question really becomes not if we're spending enough, but what it is that we happen to be buying. How much of any given $1 you spend in taxes purchases textbooks, or pays teacher paychecks? Hell, how much on air conditioning in the summer so kids can concentrate on something other than the sweat dribbling down their foreheads?
How much is spent on the office building downtown that has nothing to do with teaching directly, but with people who manage the teachers? And with people who manage those managers?
> So one should strive to eliminate private schools as much as possible. I entrenches inequality.
If the only equality you can figure out how to manage is hammering down all the nails that stick out, what good is equality?
