When it comes to working in a team, you have to consider what's fair, and you have to consider your obligations to the team itself. Perhaps the most important thing to consider is what you are promising to provide the client in exchange for what you are demading, and whether or not it is fair. If you know that the project is only going to take you ten hours to complete, but you are charging $2000 because that's the going rate, is that ethical? How do you decide the ethics of such a charge? You also have to consider how you are going to use that client's time wisely, because it is unfair to them to waste their time with excessive talk and irrelevant details. Finally, when distributing the labor amongst the group, it is important to be fair. Even in college I have been in groups where one person establishes themselves as the "Director" and they don't do anything themselves. That's very unethical when you have no more authority over a project than anyone else in the group. And I'm not saying that it isn't OK to have a group leader, but that person should be putting in as much work as everyone else.
