At a county fairground in Wise, Va., I witnessed people standing in lines that stretched out of view, waiting to see physicians who were stationed in animal stalls. The event’s organizers, from a nonprofit called Remote Area Medical, told me that of the thousands of people who came to this three-day clinic every year, some had health insurance but did not have enough money in the bank to cover their out-of-pocket obligations. Maybe that is what medicare should cover, the fixable!
