There you go again. First, customer cannot "flow freely between insurers" as they will have been dropped from their company health plan onto public option.
It's becoming pretty clear that you're not familiar with how the health care markets work today or what the reform law does to it. So let's have a little crash course.
Broadly speaking, there are two markets for health insurance: the group market and the individual market. If you're getting a plan through your employer, you're in the group market. You're subsidized by the government and enjoy certain HIPAA protections against pre-existing conditions exclusions, unreasonable rate differences based on health status and things like that. Those protections have existed for over a decade.
The individual market, on the other hand, is where people who don't get coverage through work go to buy policies. They don't get the government subsidy that people in the group market get (which is especially significant because people who don't get coverage through their job are often lower-income than their peers in the group market), they often don't enjoy the consumer protections that people in the group market have, and it's generally a very opaque marketplace.
One of the primary goals of the insurance market reforms in the law is to make the individual market look a bit more like the group market. And it does that by creating a new structure through which individual policies are sold:
the health insurance exchange. This is a transparent marketplace, governed by certain consumer protections, where you can buy quality insurance.
If your employer drops coverage, that means you leave the group market and shop for plans in the exchange (there are even provisions for doing this voluntarily: 1) certain employers can take their employees into the exchange to shop if they choose to and 2) free choice vouchers are available if your premiums through work are high enough--these let you take your employer's contribution and buy your own plan in the exchange). You don't get dumped on the public option--note that there
isn't even a public option on the books at this time so that suggestion makes no sense. What happens is, you enter the exchange and pick the plan you like from a menu of options. If a public option existed, it would be one of the choices on that menu of options.
So, yes, customers can freely flow between plans in the exchanges.
Do providers have "wasteful spending"? Really? Any evidence for that, that the cost of healthcare is due to waste?
This is health economics 101. First of all, part of the reason I quoted that section of the MedPAC (and I suggest at some point you actually read it, it's interesting stuff) is because this is exactly what they're talking about. That said, last year
Thomson Reuters put the number at $650-$800 billion per year. But the obvious inefficiency of medical providers is no less important than their 182% (on average) markup of services over the actual cost of treatment.
As I've said in
another thread, there is at least one alternative to the public option that I think would probably be even more effective than it.
They will increase their demands on private insurers because they will need to make up lost revenue from government reimbursements.
To reiterate: you can't cost shift from A to B when people in B can simply go to A. Cost shifting requires immobility on the part of those who're on the short end of the stick.
Let me ask you this: do you believe the American health system is as efficient right now as it can possibly be? That providers are charging exactly what they need to charge to sustain and flourish, with a healthy profit margin for those providers who are for-profit? In other words, do you think there is absolutely no health care cost problem in this country?
This is already the case, as you yourself admitted. Public option will make it worse, not better.
You're either not reading what I'm saying or not understanding it. I assume it's a little of both.
