But how would we actually go about achieving that goal in the actual world we live in? Well, we'd have to raise taxes[2], and a solid third of US citizens would veto any raise in taxes for any reason whatsoever, and another 50% or so would veto raising teacher salaries on tribal affiliation grounds (I'm assuming a fair amount of overlap between these groups), meaning, you probably have at least a solid plurality against the idea[1]. Not to mention the difficulty of how a city like Stockton, CA (now bankrupt) could achieve such a goal.
I hate to be so pessimistic, but I tend to believe that anything beyond tinkering with the margins of the school system is unlikely and probably politically impossible.
[1] For example, in Austin, TX, 2/4 of the last round of AISD bond initiatives passed, by very slim margins. And Austin is a rather liberal city.

[2] Edit: or cut other things, in which case we're back to the same debate that's more or less immobilized our country for the last few years, thus illustrating my point.
