The flat tax plan and others being discussed that would cut even deeper would be windfalls for the wealthy, and expensive ones at that. Families with incomes over $300,000 per year, for example, could expect to gain, as a group, about a billion dollars annually under the flat tax plan. If you asked Ohio families about their top priorities for this legislative session, it’s a safe bet that very few of them would choose a billion-dollar tax cut for this group over funding for schools, parks, and infrastructure.
