BOSTON, Sept 8 (Reuters) - 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.
