I have no idea. Can you expand on that?
Sure! 70% of Americans have government-subsidized employer-provided health insurance. In almost every case, the employer pays some portion of the premium, since they will receive a subsidy from the government in the form of a tax exemption for doing so. Often that portion is 100%.
As a result, an analysis that compares the out-of-pocket cost to the tax increase is not necessarily reasonable. Most Americans have no exposure to the out-of-pocket cost of their insurance, because it comes as wages in kind. Nor is it safe to assume the removal of those wages in kind will lead to the corresponding increase in wages in cash, because those are sticky.
It is quite possible that the actual experience for most Americans will be a loss of their current health insurance provisions, no corresponding wage increase, and a noticeable tax increase. That doesn't mean we shouldn't do it, but we should be clear about the outcome.
