very interesting (though reformist!) essay in The Nation on Michigan, the MDOC, and the proposed Good Time Bill
Michigan’s Prison Crisis by Jacqueline Williams

"Michigan has one of the longest average criminal sentence lengths in the country. The disparity is driven by several factors, one of the largest being that, since 1998, Michigan has been one of two states that provide no ability to earn time off a sentence: no disciplinary credits, no productivity credits, no 'good time.'
Michigan used to offer different forms of earned-time incentives, but a 1978 ballot initiative removed the majority of our 'good time' credits, and then the 1994 Crime Bill provided financial kickbacks for states that adopted 100 percent 'truth in sentencing'—a failed policy that requires people to serve every single moment of their original sentence, despite institutional behavior, achievements, and productive rehabilitation. This ushered in an era of mass incarceration in our state and throughout the country."
