The Uninsured Americans...Exaggerated?

Is there a real problem with the uninsured in America or is it being exaggerated? It seems to be a big question lately. Studies show that there are approximatley 40 million unisured people living in the United States. Of which are 14 million illegal undocumented. Another 10 million are under the age of 30 and for a variety of reasons chose not to partciate in medical programs that are offered to them. Kind of the superman complex...nothing can happen to me. So if these numbers are believeable, there are about 16 million American citizens that are do not have amedical benefit program. Approximately 5% of American citizens? Is this an epidemic? Would it make sense to expand government programs for people? Is this why there is little movement from the government to solve this issue?
