General Motors is in U.S District Court today asking a federal judge to help it save a billion dollars a year on health care costs by charging hourly retirees monthly contributions, deductibles, and co-pays. The deal will cost the average retiree a maximum of $370 a year. Some retirees are hopping mad. Others indicate that in a world where General Motors lost $8 billion last year, sacrifices may be necessary if the automaker is to survive. Michigan Radio’s Jack Lessenberry spoke with Sean McAlinden the chief economist at the Center for Automotive Research.
