The widening gap between America's wealthiest and its middle and lower classes is "unsustainable", but is unlikely to improve any time soon, according to a Harvard Business School study released on Monday. The study, titled "An Economy Doing Half its Job", said American companies - particularly big ones - were showing some signs of recovering their competitive edge on the world stage since the financial crisis, but that workers would likely keep struggling to demand better pay and benefits. "We argue that such a divergence is unsustainable," according to the report, which was based on a survey of 1,947 of Harvard Business School alumni around the globe.
Some 47 percent of respondents in the survey said that over the next three years they expected U.S. companies to be both less competitive internationally and less able to pay higher wages and benefits, versus 33 percent who thought the opposite. Harvard called on corporate leaders to help solve America's wealth gap by working to buttress the kindergarten-to-12th-grade education system, skills-training programs, and transportation infrastructure, among other things.
