Say something like Medicare + 5%. The obvious point is that we can adjust reimbursement rates (and get rid of fee for service BTW) and still have a much less costly program. The whole point is that Medicare has incredibly low administrative costs because there is no CEO looking to buy another mansion, no private jet, no lavish corporate headquarters, no marketing or advertising, no shareholders and no lobbyists handing out money.
It's common sense we're talking here. Another benefit Cenk didn't mention is that this would rescue Medicare, which was only struggling because it had the oldest/sickest population which is not how an insurance pool is supposed to work. Oh, and Medicare Part D bars negotiating drug prices. That would be critical to fix at some point as well.
