Former Republican vice presidential candidate Paul Ryan says that Detroit’s chapter 9 bankruptcy is a warning to the U.S. and compares the Motor City to the NBC post-apocalyptic drama “Revolution,” The Detroit News reported yesterday. In a new memoir, the Wisconsin Republican who chairs the House Budget Committee, recounts Detroit’s collapse, along with General Motors’ decision to close its assembly plant in his hometown of Janesville. Ryan calls Detroit “a warning about what our country might face if we do not rethink how we are governing ourselves: a place full of good people with lots of potential lost amid the wreckage of bad policies and failed leadership…. If we keep it up we risk following in the path that left Detroit ravaged.”
