I also have faith in William and Catherine as the future of the monarchy, I think and hope they will do their best to instil their children with the right values. I really think they understand what's at stake after the Andrew debacle they must get rid of the dead wood to ensure its survival. On balance, I'd rather have a very slimmed down monarchy than a president.
Sweep aside royal families and sometimes the population gets something as bad if not worse. The French Revolution was bloody and vicious in the end most of the instigators were guillotined. Napoleon followed the French royal family and he went one better and crowned himself Emperor. Russia meanwhile got the Bolsheviks that went well
Umpteen political dynastic families both past and present to add to the ones already listed. Gandhis, Bhuttos Trudeaus, Kennedys, Bush family, Marcos and Duterte, (Philippines) Assad, Sadam Hussein.
