Why doesn't the Queen have any power any more?

Firstly, ask yourself this... why is the queen in power? Kings and queens are of "royal blood", they are typically chosen by a God to rule a country. That is why when the King and Queen have a son or a daughter, they are called prince and princess. They will grow to be Kings and Queens. If one of these prince or princesses is a serial killer psycho then the whole country is SOL.

We are living in the 21st century and we no longer believe in that kind of rulers.

There have been Kings and Queens in the past who have murdered their people and caused more suffering then good.

Kings and Queens are iconic now, but they FORTUNATELY contain no power.
