Hillary Clinton Is Right: The Obamacare ‘Cadillac Tax’ Is a Lemon

Hillary Clinton upended the delicate consensus on health care policy in the Democratic Party’s upper echelons this week.

Clinton reportedly came out against the so-called “Cadillac tax,” adding her voice to a bipartisan call ranging from Bernie Sanders to conservative House Republicans, from business to labor, to repeal the excise tax on high-cost employer health plans (40 percent on every dollar above $10,200 a year for individuals and $27,500 a year for families).

The elite pushback has been intense.

The Washington Post editorial board said Clinton “canceled out any claim to responsibility” on health care, and suggested she only made the decision to appease unions, which generally have good employer health care plans. One hundred and one center-left economists signed onto a letter to Congress opposing any change to the Cadillac tax without some alternative “that would more effectively curtail cost growth” in employer health plans. And Sarah Kliff at Vox presented the prevailing opinion that labor and business hate the law “because it’s working.”

Kliff bases her opinion on a study of 2014 employer health benefits by the Kaiser Family Foundation, showing that 13 percent of large companies have already downgraded their benefit packages to avoid the tax, and 53 percent have researched the possibility. The tax doesn’t take effect until 2018.

The Kaiser survey certainly shows that employers are giving worse health plans to their employees. But that doesn’t actually show the Cadillac tax is working, at least not fully, because the tax has two goals. One is to lower overall health costs by creating more monetary pain for high-cost plans, and nudging businesses and individuals to be smarter health care shoppers. The other is to boost worker pay.

The theory here is that, as employers lower health care spending, the savings get plowed into higher wages, equalizing overall compensation. Economic studies have typically looked at this the other way around, finding a relationship between falling wages and rising health care costs. “In the long run if insurance costs rise, they will take a toll on wages,” said Paul Starr of Princeton University. “The reverse should be true — in the long run, but in the short run maybe not.”

The problem with this reverse-engineering is that it’s highly theoretical. There’s no study, for example, showing that the large companies that already downgraded employee health plans also boosted wages. It would be hard to know even how to design such an experiment, given all the factors that go into wages. “I don't think there is any real research to document or refute that claim,” said Harold Pollack of the University of Chicago, one of the academics who signed the pro-Cadillac tax letter. “It is well-grounded in economic principles but difficult to empirically test.”
