A little Michigan context

This article in The Nation about the war on drugs offers a little context related to spending on incarceration in Michigan:

Over the past three decades, California has tripled the number of prisons it operates, has more than quintupled its prison population and has gone from spending $5 on higher education for every dollar it spent on corrections to a virtual dead-heat in spending. That puts it in the same boat as Michigan, Vermont, Oregon, Connecticut and Delaware–all of which, according to estimates by the Pew Charitable Trust, spend as much or more on prisons than on colleges. California is also under federal court order to implement costly improvements in the delivery of medical and mental healthcare services in prisons and to release close to a third of the prison population–about 55,000 inmates–to improve conditions for those remaining behind bars.
