The government is certainly taking a lot more control of it. I trust big insurance more than I trust big government (granted, neither one is particularly trustworthy). Besides, libs (such as Tom Harkin) admit that the current arrangement is a 'starter home' on single payer.
You sell this as a way to keep insured people from subsidizing uninsured people. Currently, virtually everyone who can afford insurance already buys it. So, taxpayers give money to the takers so they can buy insurance and the result is exactly the same as it was before. Except for the goverment getting to control it, that's the only difference.
