Basically, Jack Welch was in the right place at the right time, probably (almost definitely) played semi-legal accounting games to beat analyst estimates (a practice which later led to accounting fraud charges [2]), and pretty much mortgaged the company's future in exchange for short-term boosts by selling off many of its business units and focusing on GE Capital, which basically got annihilated a few years after Jack left. So he was also a master of leaving other people holding the bag. Also, the man was apparently (according to many people who worked with him) a massive asshole with a huge ego problem and would epitomize every negative stereotype of white male executives if he were still alive today [3].
