M-Form Society is a term that describes the demographic distribution of wealth in a society in which the statistical curve appears roughly in the form the letter "M". The term was first used in the writings of William Ouchi - "The M-Form Society: How American Teamwork Can Recapture the Competitive Edge." Subsequently in 2006, it was used again by the Japanese economist and corporate strategist Kenichi Ohmae (大åÂÂç Âä¸Â) in his work. According to his observation, Ohmae argued that the structure of Japanese society has emerged into a 'M-shape' distribution. It refers to a polarized society with the extreme rich and the extreme poor.
