Of the plans that states have hatched for the Affordable Care Act, none has been bolder than that of Vermont, which wants to implement a single-payer health-care system, along the lines of what you might find in Britain or Canada. One government-operated system will cover all 620,000 of Vermont's citizens. The hope is that such a system will allow Vermont to get costs down closer to Canada's, as well as improve health by coordinating care and ensuring universal coverage.

Just two small issues need to be resolved before the state gets to all systems go: First, it needs the federal government to grant waivers allowing Vermont to divert Medicaid and other health-care funding into the single-payer system. And second, Vermont needs to find some way to pay for it:

Now comes the big challenge: paying for it. Act 48 required Vermont to create a single-payer system by 2017. But the state hasn't drafted a bill that spells out how to raise the approximately $2 billion a year Vermont needs to run the system. The state collects only $2.7 billion in tax revenue each year, so an additional $2 billion is a vexingly large sum to scrape together.
Vermont is a middling-tax state, as states go. And that's not an accident; its population consists of longtime Vermonters, some of whom vote Republican (at least for governor) and are not super-tax-friendly, and transplants from Massachusetts and New York state, who, last time I looked, had moved to Vermont partly because the taxes were lower. Paying for this program would likely make Vermont the highest-taxed state in the nation, by quite a lot.

Now, you can argue that people should be glad to make this trade-off, not just for peace of mind, but because they will trade higher taxes for lower (no) insurance premiums. You can also argue that poor people in America should be laughing and dancing and singing all day because every one of them is economically better off than starving farmers in drought-ridden regions of Africa. Neither argument will do you much good, however, because that's not how people think.

Especially when you consider that estimates for this plan's cost are likely to err on the optimistic side, because, well, people drawing up proposed budgets for their pet ideas tend to be a little optimistic. Yes, yes, there may be fabulous cost savings from using the government's monopoly buying power to bargain prices down with providers. But Vermont is already the beneficiary of significant monopoly buying power: One insurer has 74 percent of the state's small-group business. It's a Blue Cross/Blue Shield, so don't count on fabulous savings from squeezing out profits. The large group market is even more concentrated, though on a for-profit insurer.

Nor can you get much administrative saving at the provider level, because they still have to deal with out-of-state insurers quite a bit. And the once-vaunted fabulous savings from preventative care have mostly turned out not to exist.

So this is going to be expensive. So expensive that I doubt Vermont is actually going to go forward with it.

This should be instructive for those who hope -- or fear -- that Obamacare has all been an elaborate preliminary to a nationwide single-payer system. It isn't. The politics are impossible, and even if they weren't, the financing would be unthinkable.

In 2011, the Vermont state government enacted a law functionally establishing the first state-level single-payer health care system in the United States. Green Mountain Care, established by the passage of H.202, creates a system in the state where Vermonters receive universal health care coverage as well as technological improvements to the existing system.

On December 17, 2014, Vermont Democrats abandoned their plan for universal health care, citing the taxes required of smaller businesses within the state.
