So what does the president have to offer the Midwest? The idea that the wave of the future is an ever-larger public sector financed by a more or less stagnant private sector looks increasingly absurd. The Midwest’s public sector has, as Margaret Thatcher put it, run on “other people’s money.” Meanwhile, Mr. Obama’s trip to the Midwest has been preceded by Texas Gov. Rick Perry’s foray into Waterloo, Iowa. Mr. Perry points out that his state, with low taxes and light regulation, has been producing nearly half of America’s new jobs.
