According to a recent report by Forbes.com Dallas-Ft. Worth is ranked fifth in terms of generating white collar jobs. According to Forbes the Texas powerhouse’s business services workforce has expanded 28.9% since 2010 to 458,200. The Dallas-Ft. Worth area has plenty of appeal to big companies with a large cohort of middle-income managers, as a paper to be published this fall by Southern Methodist University’s Klaus Desmet and Cullum Clark well describes. These jobs pay well enough to live well in Dallas’ nicer suburbs, such as Plano and Frisco, but not remotely enough to buy a house, or even a condo, in Los Angeles, San Francisco or New York.This accounts, in part, for the relocation of Toyota America’s headquarters from Torrance, Calif., to the north Dallas suburbs, and likely plays a role in the plans of Jacobs Engineering, a longtime fixture in Pasadena, to relocate its headquarters to downtown Dallas.
