A recent study by Watson Wyatt–Retiree Health Benefits: Time to Resuscitate?–contains data regarding the future of retiree medical benefits:
Future retirees will shoulder substantially more ? if not all ? of the costs of their health care in retirement. Watson Wyatt estimates that the level of employer financial support will drop to less than 10 percent of total retiree medical expense by the year 2031, under plan provisions already adopted by many employers.
Also, a recent article on the topic from the National Law Journal: “Benefits as Burdens.” (At the end of the article, there is a quote from this author.)
