Harvard confirms findings Piketty

'An economy doing half its job', that's the title of a recently published survey of the famous Harvard Business School. The report of Porter & Rivkin confirms the findings of the French economist Thomas Piketty: the rich get richer and the middle class and the poor get poorer. Firms should have a strategy in which humans count. Social responsability is the key. A summary is available on the site of 'Les Echos'.
