A good question about Medicare "reform"

It's Not Demagoguery If It's True: "But wait, you might be saying -- isn't Medicare less expensive than private insurance, since Medicare spends so little on overhead and administration, while private insurance spends so much (not to mention what has to be set aside for profits)? And isn't this supposed to be a plan to balance the budget? So how do you take less expensive Medicare, turn it into a voucher program for more expensive private insurance, and save money?"
