There’s a simple reason why Illinois Democratic candidates for governor don’t get specific about the progressive income tax they all want: The numbers immediately expose why it’s not the magic bullet their reality-challenged progressive supporters imagine. Just as we saw with the recent income tax hike, we’d just be putting more money into a bottomless pit. Some light emerged on this topic last week. Bob Dailber is a downstate Democrat running for governor you never heard of. He, alone, got specific, proposing a tax cut for everybody earning less than $150,000 per year and progressively higher rates on higher earners.
