Apartheid education, rarely mentioned in the press or openly confronted even among once-progressive educators, is alive and well and rapidly increasing now in the United States.

The contrasts between what is spent today to educate a child in the poorest New York City neighborhoods, where teacher salaries are often even lower than the city averages, and spending levels in the wealthiest suburban areas are daunting challenges to any hope New Yorkers might retain that even semblances of fairness still prevail.

By far the most important factor in the success or failure of any school, far more important than tests or standards or business-model methods of accountability, is simply attracting the best-educated, most exciting young people into urban schools and keeping them there.

Nationally, overwhelmingly non-white schools receive $1,000 less per pupil than overwhelmingly white schools.
