Quick, let's make a deal (before the deficit goes away on its own)

[T]he big stick for the deficit hawks was their story of huge deficits in the longer term. They attributed these to the rising cost of “entitlements,” which are known to the rest of us as Social Security, Medicare, and Medicaid.

While they like to push the notion that the aging of the population threatened to impose an unbearable burden on future generations, the reality is that most of the horror story of huge deficits was driven by projections of exploding private sector health care costs. Since Medicare and Medicaid mostly pay for private sector health care, an explosion in private sector health care costs would eventually make these programs unaffordable.

As some of us have long pointed out, there are serious grounds for questioning the plausibility of projections that the health care sector would rise to 30 or 40 percent of GDP over the rest of the century. Recently a paper from the Federal Reserve Board documented this argument in considerable detail.

Even more important than the professional argument over health care cost projections is the recent trend in health care costs. While the CBO projections assume that age-adjusted health care costs rise considerably more rapidly than per capita income, in the last four years they have been roughly keeping pace with per capita income.

In fact, in the last year nominal spending on health care services, the sector that comprises almost two-thirds of health care costs, rose by just 1.7 percent. This is far below the rate of nominal GDP growth over this period, which was more than 4.0 percent. While at least some of this slowing in health care costs is undoubtedly due to the downturn, it is hard to believe that it is not at least partially attributable to a slower underlying rate of health care cost growth.

CBO and other budget forecasters can ignore economic reality for a period of time (they ignored the housing bubble until after its collapse wrecked the economy), but if it continues, at some point they will have to incorporate the trend of slower health care cost growth into their projections. When this happens, the really scary long-term deficit numbers will disappear.

A projection that assumes that health care costs will only rise as a result of the aging of the population, and otherwise move in step with per capita income, will lop tens of trillions of dollars off the most commonly cited long-term deficit projections. It would cost some deficit hawks, like National Public Radio, more than $100 trillion of their long-term deficit story. This would be a real disaster for the deficit hawk industry.

This is why the Campaign to Fix the Debt and the rest of the deficit hawk industry will be operating at full speed at least until a budget deal is reached over the current impasse. If CBO adjusts its long-term health care cost projections downward then their whole rationale for gutting Social Security and Medicare will disappear. Now that is really a crisis.
