TRAMECKSANS VS SLAMECKSANS:

The rationalization and extension of the current market is financed by the other linchpin of the law: the mandate that we all carry health insurance, an idea forged not by liberal social engineers at the Brookings Institution but by conservative economists at the Heritage Foundation. The individual mandate recognizes that millions of Americans who could buy health insurance choose not to, because it requires trading away today's wants for tomorrow's needs. The mandate is about personal responsibility -- a hallmark of conservative thought.

IN the partisan war sparked by the 2008 election, Republicans conveniently forgot that this was something many of them had supported for years. The only thing wrong with the mandate? Mr. Obama also thought it was a good idea.

The same goes for health insurance exchanges, another idea formulated by conservatives and supported by Republican governors and legislators across the country for years. An exchange is as pro-market a mechanism as they come: free up buyers and sellers, standardize the products, add pricing transparency, and watch what happens. Market Economics 101.

In the shouting match over the health care law, most have somehow missed another of its obvious virtues: it enshrines accountability -- yes, another conservative idea. Under today's system, most health insurers (and providers) are accountable to the wrong people, often for the wrong reasons, with the needs of patients coming last. With the transparency, mobility and choice of the exchanges, businesses and individuals can decide for themselves which insurers (and, embedded in their networks, which providers) deserve their dollars. They can see, thanks to the often derided benefits standardization of the reform act, what they are actually buying. They can shop around. And businesses are free to decide that they are better off opting out, paying into funds that subsidize individuals' coverage and letting their employees do their own shopping, with what is, in essence, their own compensation, relocated to the exchanges.

Back when the idea of letting businesses and consumers pick their own plans -- with their own money on an exchange -- first floated around Washington, advocates called them "association health plans." They, too, would have corrected for the lack of transparency, mobility and choice in local insurance markets by allowing the purchase of health insurance across state lines. They were the cornerstone of what would have been the Bush administration's reform plan (had the administration not been distracted by other matters). After the rejection of "Hillarycare" in the mid-'90s, association health plans emerged as the centerpiece of pro-market, Republican thinking about health reform -- essentially what would become Romneycare, extended via federal law to cover the entire country. So much for Mr. Romney's argument that his plan in Massachusetts was an expression of states' rights. His own party had bigger plans for the rest of the country, and they looked a lot like Obamacare.

But perhaps the clearest indication of the conservative economic values underlying the act is its reception by many Democrats. The plan has few champions on the left precisely because it is not a government takeover of health care. It is not a single-payer system, nor "Medicare for all"; it does not include a "public option," a health plan offered by a federal insurer. It is a ratification of market ideas, modified to address problems unique to health insurance.

Mr. Obama's plan, which should be a darling of the right for these principles, was abandoned not for its content, but rather for politics.
