Ryan's plan is mostly a means to shelter those who have already benefited from a half-century of fiscal irrationality and dump the burden on those who are to come later. Under Ryan's plan, traditional Medicare will only be available to people who are already on it or less than 10 years away. Ensuing generations would instead be given government vouchers and tossed out into the very health insurance market that has gobbled huge portions of the private economy and given us the worst health-care outcomes in the developed world.
