The Hackett Group, a consultant on back-office jobs, estimates 2 million of them in finance, human resources, information technology and procurement have disappeared in the U.S. and Europe since the Great Recession. It pins the blame for more than half of the losses on technology. These are jobs that used to fill cubicles at almost every company â¿¿ clerks paying bills and ordering supplies, benefits managers filing health-care forms and IT experts helping with computer crashes."The effect of (technology) on white-collar jobs is huge, but it's not obvious," says MIT's McAfee. Companies "don't put out a press release saying we're not hiring again because of machines." ___ What hope is there for the future? Historically, new companies and new industries have been the incubator of new jobs. Start-up companies no more than five years old are big sources of new jobs in developed economies. In the U.S., they accounted for 99 percent of new private sector jobs in 2005, according to a study by the University of Maryland's John Haltiwanger and two other economists. But even these companies are hiring fewer people. The average new business employed 4.7 workers when it opened its doors in 2011, down from 7.6 in the 1990s, according to a Labor Department study released last March. Technology is probably to blame, wrote the report's authors, Eleanor Choi and James Spletzer. Entrepreneurs no longer need people to do clerical and administrative tasks to help them get their businesses off the ground. In the old days â¿¿ say, 10 years ago â¿¿ "you'd need an assistant pretty early to coordinate everything â¿¿ or you'd pay a huge opportunity cost for the entrepreneur or the president to set up a meeting," says Jeff Connally, CEO of CMIT Solutions, a technology consultancy to small businesses. Now technology means "you can look at your calendar and everybody else's calendar and â¿¿ bing! â¿¿ you've set up a meeting." So no assistant gets hired.
