Is this seriously what you have descended to? Have you forgotten EVERYTHING anybody ever told you about health care economics?
Yes, okay, Klein was arguing with Megan McArdle. That's an inherently difficult task: it's rough to debate economics and policy with someone who hasn't the faintest clue about anything—least of all economics and policy. But that's no excuse for saying "I think seniors should just be given cash instead of Medicare". There IS no excuse for that.
