Matthew Yglesias counters that the health care industry in Pittsbrugh requires lots of low-wage workers, which is true. But in addition, any hospital needs lots of nurses, who make decent middle-class to upper-middle class wages and are certainly not considered blue collar. Meanwhile, someone has to keep the buildings clean at Boeing and Microsoft, though there certainly isn't as much cleaning to do in an office park as there in a hospital. And it's not clear how we should count call center workers, internal tech support, and other tech-sector jobs that pay wages somewhere middle-class and "working class". But we can argue about it, or we can look it up. Returning to the Census employment survey, the percentage of workers describing their job as "service" in Pittsburgh is 16%, and in the Seattle is ... 14%. Perhaps lots of staff workers, billing professionals, and research assistants at Pittsburgh's medical centers count themselves as having "managerial, professional and related occupations" despite not making that much money; perhaps to the huge barista population in Seattle is raising the city's service number. The data seems inconclusive; we could use better information on the income distribution for workers in the health care sector.
