I think the employer-based system was on its way out anyway - with or without ObamaCare. When I started at the company I work for now, there were NO premiums for health care (15 years ago). Now the premiums are over $400/month, the copays are much higher, etc... American corporations are eagerly waiting for the day when they can dump health care for their employees.
We are headed for rationed health care. That is the only way we as a country can control costs. Every other country is doing it and it completely inevitable that we will as well.
We already have rationed care, for everything desirable that costs time or treasure is inherently rationed. Right now the USA rations health care by availability via insurance and by cost, whereas countries like the UK ration health care by availability via queue and by lowering the quality of care one receives. (I.e. one sees a nurse rather than a doctor and standards are lowered for each level of provider.) But yes, I agree we're moving toward a system where government controls and rations all health care. That's why Obamacare had such corporate support. Large companies have trillions in health care commitments for current and past employees; if they can offload that cost onto taxpayers that would be an incredible boost to profitability and competitiveness.
I've previously linked a study on MRIs for Canadian heart patients. It's one of the things Canada has been working on, for right at 50% of heart patients needing an MRI dropped out of queue before their 12+ month wait was up. Some died, some became too sick to survive the surgery for which the MRI would have provided approval, some went to other countries, and some dropped out without leaving a trail. In the USA the wait is typically less than a week, even for those without insurance. (In Canada one's pet could get an MRI same day, amusingly enough.)
Which system is better depends largely on one's circumstances. If a Canadian is languishing in Canada waiting for an expensive procedure with a long queue, the American system looks mighty good. If a Canadian has a routine medical need in Canada and gets quick attention at little or no cost, the Canadian system looks mighty good. If an American has good insurance and gets immediate access to the best care in the world, the American system looks mighty good. And if an American has no insurance and cannot get expensive but non-critical care or gets good medical treatment but at the cost of financial ruin, the Canadian system looks mighty good. It's all a matter of one's current circumstances.
