Fragment of a discussion from Comments:Prince William marries Kate Middleton—live updates
I can't speak for the other countries, but Britain's a constitutional monarchy Diego, and they do rule with the consent of the people. Perhaps not all of the people, but certainly a majority - polls on this are pretty regular and hover at around 70%.
And the royal succession in Britain isn't as simple as you might think. Several times Parliament has stepped in to influence it - the Restoration, w:Glorious Revolution, and abdication of Edward VIII spring to mind.
Brits are stupid then (no offense intended, though). Do it the French way!
Been there, done that. Ended up with Cromwell et al, who did such wonderful things as genocide in Ireland, and cancelling Christmas (seriously).
