Thought of the Day - Power

In a relationship who has the most power? It has been suggested that the person with the most options or the least to loose has the power. I am more inclined to agree with the former.

Whether it be a personal relationship, your relationship with a shop, your relationship with your employer, the side with the most options has the power. But how do you define the most options, more accurately it should be the most good options. If you have more good options than the other side you should always end up better off, even if they don't relaise you have the upper hand.
