A side note to this is how detrimental many saw Eisner as he began to micromanage every aspect of projects coming out of Disney. Being emotionally invested and interested in the company like that can definitely be a bad thing and lead to the wrong decisions. Even Disney fans on the internet have difficulty agreeing on the direction they want to see the company go, and they are mostly skewed to a certain group of people. And surely you can see that as a group- they rarely have the best interests of the general population in mind.
In the end the spreadsheets and numbers can tell the story in the most unbiased fashion possible. The numbers can cut through dissenting opinions and present the truth. Just like our country is run by the numbers (votes) any good business will too.
