The September FedLetter from the Federal Reserve Bank of Chicago has an interesting graph showing the increase or decrease of employment since the beginning of the year.

...across a variety of payroll survey calculations, job growth seems to be occurring in high- and low-wage sectors in a fairly typical way given where the economy is in the employment cycle.

The authors note that while the graph above looks like most of the growth is in above-average wage areas, finer breakdowns of the industrial areas (2-digit NAICs instead of 1-digit, if you really must know) make the pattern look less positive. Still, the Kerry claim that job quality has been poor during the expansion is at least debatable; this expansion has been quite normal in the quality of jobs generated.
