The Romney-Ryan position on health care is that many millions of Americans must be denied health insurance, and millions more deprived of the security Medicare now provides, in order to save money. At the same time, of course, Mr. Romney and Mr. Ryan are proposing trillions of dollars in tax cuts for the wealthy. So a literal description of their plan is that they want to expose many Americans to financial insecurity, and let some of them die, so that a handful of already wealthy people can have a higher after-tax income.
