Maryland already has a progressive tax structure, and I never spoke out against that structure. It is fair to have a debate about the best rates within that tax structure. But what transpired on the floor of the Senate went far beyond an economic debate and policy question. In an attempt to "stick it" to the high-earners, the Senate didn't just adopt a new rate. The Senate adopted a provision, for the first time in Maryland's history, where the tax on high-earners would be applied to every dollar they earn, unlike every other tax bracket. The effect of that provision would be that an individual making $500,001 would pay close to double the tax of an individual paying $500,000. One dollar more in earnings costs close to $3,000 in taxes. That, of course, makes no sense, which is why the Baltimore Sun, in its editorial "Tax policy on the fly" (March 19), roundly criticized that same provision. But in Mr. Rodricks' world of inflexible party-first politics, does it not matter whether something makes sense at all?
