Only people who do not have power would ask question like this. :)
The governed: Hey, Dude! Why can you have the power OVER ME? Who gives you the right to do so?
The governing: Because if you don't do what I tell you, I will k**ill you or put you to jail. I have guns and the well fed bodies that hold those guns. You don't! So suck your thumb and obey.
THAT IS POWER!
