"30% can be saved from healthcare just in administrative costs" Sure, "liberal analysts" will argue that--without any evidence at all. Those savings will be just like the current Medicare savings, no doubt. My very first venture into a doctor's office after I became a captive of Medicare resulted in more paperwork than I used to see in a month with a private insurance plan and--the real treat--the doctor was paid about twice the amount of his bill by Medicare, after which Blue Cross chipped in some more money. I was assured by a Blue Cross representative on the phone that it all made perfect sense and was based on some hazy formula resulting from a "contractual arrangement". Just clerical stuff and, no doubt, part of that 30% savings. I didn't pursue the matter very far. It's impossible to decipher the administrative hallucinations that are Medicare.
You don't give a source for your "three to ten times more administratively efficient". If you can come up with one, it'll be from some government agency or Congressional committee staff, or a liberal "think tank". You will never see one single thoughtful conservative economist dispute these numbers, because: 1) you will declare anyone disputing them not to be sufficiently "thoughtful"; and 2) most conservative economists produce reasonable models with reasonable conclusions and don't waste a lot their time in a vain effort to tear down every illusory facade the left can erect. But keep quoting those fantasy statistics: 30% savings sounds real good!
