But all the jobs being created are minimum wage
It is a perception all the more remarkable for the data it lacks.
Below is a long term time series of how local personal income per capita compares to the nation's. For 2012 local personal income per capita is 9.4% over the national average. So yes, Pittsburgh's income of late is better than it has ever been in the modern era, as it were. That includes the period before steel jobs collapsed. If there was a period in the past that we (briefly) compared favorably to the nation, though not as good as today, it was the late 1970s. To understand that period you have to unpack the experimental negotiating agreement (ENA) agreed to between the steel industry and its workers, but that is a longer story for another day.
Don't get this wrong. For the individual steelworkers who lost their jobs, their incomes went south in most cases for the remainder of their working careers, but on average across the region the wages being earned today compare better to national norms than ever before. That says a lot about the jobs, the quality of jobs if you wish, that have been created here over the last decade compared to jobs that were common here in the past. To pull up the average that fast means the marginal jobs, the new jobs, must be much better paying than was common in the past. More to the future, it sure looks like the trends are continuing upwards as well.
