Neither of you wizards seem to comprehend that the problem is BOTH.
Attempting to educate the uneducable is a WASTE of education dollars, AND it
made American women the laughing stock of nations.
We spent an EXTRA $8 trillion to attemp to educate the uneducable
(increasing education spending as a percent of GDP from 4% to 8%), and what
happened? SAT Scores plunged 98 points, leaving us DEAD LAST in 17 of 34
TIMSS problems
And what happened to women? On ONE THIRD of one section of the test,
American girls would have scored higher if they had just guessed, rather
than trying to solve the problems.

Do you comprehend the problem now? No? Is it any wonder?
