Once again, Republicans have proposed privatizing Medicare, despite the rather chilly reception this transcendently idiotic idea received last time. The logic is, as always, is that the hallowed Private Sector just does everything better than that wasteful, extravagant, ol’ Big Gummint, so why would caring for sick old people be any different? I won’t bore you with inconsequential minutia about risk pools, demographics, or, well, what makes health insurance pencil out as a business proposition, but I wish that, for once, they’d give an example wherein this cockamamie notion actually worked.
