I’ve gotten a few requests about Ohio’s private sector since Amity’s column opens with a discussion of President Obama’s recent trip to Ohio. Below is chart comparing Ohio with New Hampshire. In many respects, this is an even starker contrast since OH’s per capita personal income and private sector were greater than NH’s until the late 1970s. First OH’s private sector plunges below NH’s and then a few years later so does OH’s per capita personal income. Is it a mere coincidence that all of this occurs in the years immediately following the enactment of OH’s income tax in 1971? You decide.
