In politics, as in life, we all have desires and contend with obstacles that keep us from getting what we want. A government’s rules and laws, for example, limit what we can do. Those in power differ from the rest of us: they can design rules to their advantage and make it easier for them to get what they want. Understanding what people want and how they get it can go a long way to clarifying why those in power often do bad things. In fact, bad behavior is more often than not good politics.
