Why does everyone think they could be a better boss?

People love to have an opinion or the power to make a call which is why being a boss seems so appealing...  Free will right? Not really...  Because as a boss you need to have opinions on things which you don't care about,  aren't interested in,  and have to make calls which are big in nature when you don't feel like it.
There's no more or less free will having power, it's just what you do and don't have power over shifts.
