Jobs growth in the U.S. since the 2008 recession has been undermined by lower wages, with workers earning an average 23 percent less than earnings from jobs which were lost, a report by an organization representing U.S. cities said on Monday. The average annual salary in sectors where jobs were lost – particularly manufacturing and construction – during the 2008-9 financial crisis was $61,637, according to the report by the United States Conference of Mayors (USCM), which represents cities with populations of more than 30,000.
