Ecto states a valid fear but in the wrong way, the lack of choice comes from the fact that a middle class citizen, or a small business, could not afforad both the new high taxes for the public healthcare system and the cost of insurance or direct pay toward a more accountable private healthcare.
As usual the issue boils down to it benefiting the folks who lack the means to pay for their own now versus hurting the quality of service for those who can.
My stance still happens to fall on the "It's not my societal responsibility to pay for the private services of others." side of things, but we've been slowly losing that fight for the last... long time. (I'd launch into the whole 'any society that can vote itself money is doomed to fail' quote rant, but I won't post in this thread again for a while more than likely.)
(edit: hey Jay, ask Great Brittain how national healthcare works for retaining their doctor levels in the country. It pays so little they have to do those 'look the other way and speed along the naturalization of foreign doctors' kind of things to keep the level ballanced. It's a profession that requires a ridiculous ammount of training and certification, and when you remove the monitary insentive, you're killing a LOT of the supply. You have two choice at that point, pay them more [higher taxes in a social system, higher prices in a public one] or remove a level of difficulty required to get a lisence [Dr. Nick Riverra's Holleywood Upstairs Medical Schoo.] Or you could always accept them as long as they're certified in Mexico. Point is, it doesn't remain all roses, and there isn't an easy and good solution. Not that I don't sympathise, but I still shouldn't be gun to the head responsible for the wellbeing of others not my family or offspring.)
