No. http://jobs.aol.com/articles/2010/11/16/c-students... C students in college tend to become the bosses. The article puts forth some hypotheses. I think it's because career advancement is as much about politics and making people like you as it is about ability.
People want to be around someone they like, and it tends to bias the judgment on that individual if bosses have more positive feelings toward them. Be more outgoing, learning how to play power relations but be less academically astute, and you are apparently on your way to success!
Studies have also shown the most successful executives may actually lack the ability to empathize in the same way that other people can. http://www.huffingtonpost.com/2011/12/22/rich-peop... It's also interesting that the end of the article shows the "titans of industry" may actually have to make decisions with a complete disregard for human suffering in order to increase the bottom line. Sorry I got off track here.
