Universal preschool has become the ginseng of American politics, a sort of broad-spectrum nostrum that will cure almost anything that ails you. Inequality, male-female pay gaps, crime, poverty — just apply some early childhood programs, and watch those maladies fade. Expect to hear this a lot from Hillary Clinton in the coming presidential race.
And what kind of a crotchety, sour, greedy old columnist could be opposed to such a wonderful idea? I’m so glad you asked.
In truth, I am not opposed to early childhood education programs. I am opposed to blind boosterism of such programs, the kind that confidently predicts marvelous results from thin empirical evidence, and briskly proceeds to demand huge sums be spent accordingly.
