What's the reason why some people hate reporting to a boss?

I feel like I know people who the main reason the have their own business is because they don't want to report to a boss. I was wondering why some people hate reporting to a boss. I don't view it as bad if someone feels that way. I'm just curious.

Personally, I just don't let bosses bother me I guess. Since, I feel like it's a two way relationship. They can't just act unfair and rude. If they fire people it wastes money and gives them a bad reputation probably. At least at the companies I've worked for I've felt that way and it's worked for me.
