Discrimination in public benefits is also perfectly legal. Under federal law, people convicted of drug felonies are deemed ineligible even for food stamps.

We have now spent 1 trillion dollars waging the drug war since it began. A trillion. Those funds could have been used for education, jobs and drug treatment in the communities that needed it most. We could have used those funds for our collective well being, instead those dollars paved the way for the destruction of countless lives, families, and dreams.

What has changed since the collapse of Jim Crow has less to do with the basic structure of our society than with the language we use to justify it. In the era of colorblindness, it is no longer socially permissible to use race, explicitly, as a justification for discrimination, exclusion, and social contempt. So we don't. Rather than rely on race, we use our criminal justice system to label people of color "criminals" and then engage in all the practices we supposedly left behind.

I say we haven't ended racial caste in America; we have merely redesigned it.

The war on drugs has been the engine of mass incarceration. Drug convictions alone constituted about two-thirds of the increase in the federal prison population and more than half of the increase in the state prison population between 1985 and 2000, the period of our prison system's most dramatic expansion.

I think it's critically important that the people who have been most harmed by mass incarceration, by mass deportation, by neoliberalism, by all of it, not only have a voice in crafting these platforms but emerge and are supported as real leaders in these movements.

Voting rights expert and legal scholar Pam Karlan reports that as of 2004, there were more black men disenfranchised than in 1870, the year the Fifteenth Amendment was ratified prohibiting laws that deny the right to vote on the basis of race.
