The money thing, again

Pulitzer Prize winner George Will has a good column about Washington's latest foray into public education.
The money quote: "Abundant evidence demonstrates that money is not an Archimedean lever for moving the world of education. Inflation-adjusted per-pupil spending tripled over four decades; pupil-teacher ratios were substantially reduced as the number of teachers increased 61 percent while enrollments rose about 10 percent. Yet test scores stagnated or declined."
The idea of measuring public schools by the amount of money you throw at them is thoroughly discredited, but liberals continue their attempts to revive this myth. Therefore, it is necessary to counter them each time in order to drive a stake through the heart of their theory.
