Wow - had no idea this was on the cards.
I've some very real experience of this kind of thing, having lived in the UK with its National Health Service (NHS) prior to moving to California.
Let me tell you about the UK's NHS. Firstly the good - if you need to see a doctor, you will - free of charge. If you have an accident, an Ambulance will pick you up and take you to an emergancy room where you will be treated free-of charge. If you need a prescription, it will cost you no more than approximately $25. Sound great huh?
However, there's a few downsides:
Firstly, if you need to see a specialist or have in-patient care, be prepared to wait. Years.
Secondly, free-of-charge is, of course, no such thing. Direct taxation (what get's taken out of my sallary each month) is almost exactly equivalent between the UK and California. However, that's only because raising income tax is political suicide in the UK. Instead, 'Stealth' taxes are the preffered method of revenue generation. How does 17.5% sales tax grab you? Or $6 a gallon of gas?
Thirdly, there is a whole underclass of people in Britain working the benefits system who are costing the NHS uncounted millions and contributing nothing.
Healthcare in the US may seem expensive, but I'm willing to bet if I did the math my insurance costs are less than I was contributing through taxes in the UK. At least here I'm only paying for myself and my dependants. Back home I was also paying for all the leaching scum with no interest in ever working for a living.
Finally, DMV has nothing on the NHS in terms of wasteful, arrogant, useless beurocracy.
Ultimately, universal access to healthcare sounds great, but in my experince, it'll come at the expense of quality of service and huge costs to those of us who'll be paying for it.
