The Monarch is a huge income producer for the people - when you consider it a tourist attraction, producer and such - plus the peoples affection in having it you better understand why it has stood the test of time.
I think Charles will do OK because of William and Kate - the people there are really looking forward to when they assume the titles down the road.
I consider British royalty a tourist attraction. If it were not for all the money they bring in as a tourist attraction, parliament would’ve probably downplayed them years ago.
