Kids are growing up in communities in which they see their loved ones cycling in and out of prison and in which they are sent the message in countless ways that they, too, are going to prison one way or another. We cannot build healthy, functioning schools within a context where there is no funding available because it's going to building prisons and police forces.

In the war on drugs, state and state law enforcement agencies have been rewarded in cash by the federal government - through programs like the Edward Byrne Memorial Grant program - for the sheer numbers of people arrested for drug offenses.

Of course in this age of colorblindness, a time when we have supposedly moved "beyond race," we as a nation would feel very uncomfortable if only black people were sent to jail for drug offenses. We seem comfortable with 90 percent of the people arrested and convicted of drug offenses in some states being African American, but if the figure was 100 percent, the veil of colorblindness would be lost.

The fact that more than half of the young black men in any large American city are currently under the control of the criminal justice system (or saddled with criminal records) is not - as many argue - just a symptom of poverty or poor choices, but rather evidence of a new racial caste system at work.

We have not ended racial caste in America, we have merely redesigned it.

The bigger picture is that over the last 30 years, we have spent $1 trillion waging a drug war that has failed in any meaningful way to reduce drug addiction or abuse, and yet has siphoned an enormous amount of resources away from other public services, especially education.

A massive new penal system has emerged in the past few decades - a penal system unprecedented in world history. It is a system driven almost entirely by race and class.
