Mid-Incomers Suffer in Polarized U.S. Job Market: Economy

Americans at the top and bottom of the income scale are benefiting most from the jobs recovery while those in the middle are getting left behind.

Employees making above-average wages, like doctors and energy-industry workers, and those at the other extreme, including home-health aides and restaurant staff, have seen outsized gains in hiring since the jobs recovery began in February 2010, say economists at Wells Fargo & Co. and JPMorgan Chase & Co. Professions in the middle, such as financial services and specialty construction, aren’t faring as well.
