He's my ex-boss too..
The reason he was CEO of Worldcom is because it was his company, he started it. What ticks me off most is I worked for MCI before Worldcom bought us so he not only screwed up his own company, but also the ones he acquired.
I met the guy on a few occasions and can only say that he's one arrogant mofo and likes to try and intimidate people. He likes absolute power, that's why I don't buy into his line of BS.
