When President Barack Obama gave a major speech on the economy last week in Kansas, he aimed his message at a national audience.

But he also framed an issue for state legislators to consider after they convene their annual session next year.

Obama argued in Osawatomie that the U.S. needs to rethink its tax system to see that billionaires pay the same income tax rates as their secretaries.

The president didn’t mention Republican Gov. Sam Brownback or Brownback’s plan to push for overhauling the state’s tax code. Yet Obama’s speech seemed relevant.

Brownback and officials in his administration have said his tax plan will be “revenue neutral,” meaning cuts in one area will be offset elsewhere, raising questions about who will benefit and who will pay more.
