"Economist Glenn Loury argues that this extraordinary mass incarceration is not a response to rising crime rates or a proud success of social policy. Instead, it is the product of a generation-old collective decision to become a more punitive society. He connects this policy to our history of racial oppression, showing that the punitive turn in American politics and culture emerged in the post-civil rights years and has today become the main vehicle for the reproduction of racial hierarchies."
