Listening to the WBBM 780AM in Chicago, there was speculation that GM's announcement of extended closures was cover for a bankruptcy filing during that time. The idea being that people wouldn't buy a car from a bankrupt car company, so they figured they'd close the factories, declare bankruptcy, and try to work things through fast enough so that the stripped-down car company would be up and running by the time the factories they decided to keep were ready to start again.
Thanks for commenting. You might enjoy my book about Flint called "Teardown: Memoir of a Vanishing City," a Michigan Notable Book for 2014 and a finalist for the 33rd Annual Northern California Book Award for Creative NonFiction. Filmmaker Michael Moore described Teardown as "a brilliant chronicle of the Mad Maxization of a once-great American city." More information about Teardown is available at www.teardownbook.com.
