And its corollary: more money for schools equals better schools.
The correct conclusion, one unassailable on the facts, is that more money for schools equals more expensive schools. If the education improves with the additional expenditures, then it is arguable that the additional costs are worth it. But if the quality of education declines or remains constant while the cost increases, then the per-unit value of that education (the "efficiency" if you will) has decreased.
I'll leave it to you to decide whether the cost of education has increased, and whether the quality of education has risen correspondingly, remained static, or declined.
Our local editor wrote an interesting piece about public schools. A hypothetical $1,000,000 school could also represent ten $100,000 schools, one on every corner so to speak. I mentioned this to a teacher friend and immediately she allowed that this would cost too much, because ten times the number of teachers and related personnell would be required. Isn't this a rather odd thing for a teacher to say on its face? Anyway, what the educational elites have done is homogenized and mass-produced education - it is a commodity and no deviation from the desired outcome is wanted nor tolerated. Big, regional schools with a standardized product is the mandate.
In another ten years you will not recognize this country.
