And that's not addressing it, either.Well, we won't know unless it happens, right?You're not addressing my point.
The right justifies tax cuts on the basis that they will grow the economy (clearly true) enough to pay for themselves (to date, apparently never.) You're making the exact same argument that education spending will grow the economy (clearly true) enough to pay for itself (for which you are providing no evidence.)
We have two relevant data points that I am aware of:
Poland: Rebuilding the education system from the ground up with a goal of fairness didn't change the outcome.
Kansas: Throwing 10 figures at trying to improve education for the disadvantaged did nothing.
And a quasi-point: The Cultural Revolution stripped away wealth--but there's still a considerable relationship between pre-Revolution wealth and how the next generation fared. It's not as clear because educational advantages could persist.
