Many of the Commonwealth countries have Betty Windsor (aka QEII) as queen and she and her family do indeed contribute a lot, for example:
Having a King or Queen means we can have the image of real live people on our currency, stamps and of course hanging in the local post office.
The Royal Family provide a very useful service opening hospitals, universities and childrens' play areas, they are also good at pinning on medals and sometimes the Queen gets busy dubbing folks.
The Royal Family provide a never ending soap opera for the entertainment of the masses.
Unfortunately humans NEED leaders, and Kings, Queens and down the line have been a major part of humanity.
People go gaga over those that that claim to be of royal heritage, WHY, most come from disposed family's and have to live on their tital-------Zaza Gabores husband, is a grand example.
Interesting that the Royalty of England has had such scoundrels and such Great leaders. True blue everyday folks that will willingly give up the throne for love, or kill to get it.
Fascinating people, the pomp and circumstances, the rules of the court, the pageantry of the ceremony's, the lives others lead that few others ever get to see or be part of.
The Royalty has been forever a place for special people, us underlings can only guess at. Fortunately for most they never had to live under the rules and regulations of a Royal, poor Diana found that out .
English royalty has kept tradition alive, the people may complain about taxes but when the Royal horse drawn carrage, the horse back Nights of the Guard escort it, they cheer as hundreds of years of tradition pass by.
England lives only by the Traditions of hundreds of years ago, take any of these away and England will fall, the Country that the sun never set on.
The Queen has little power except to advise and represent her country most every day, hell of a job for a woman her age, but she does it .
Her Mum and dad did the unexpected in WW2 They stayed with their people in London when the city was being bombed, sent their kids to safety and stayed with their people as London was burned. They did not leave their people to their fate, they stood with them to live or die with their people-------No boogieing out to a safe place, these people were LEADERS.
I have great respect for the Crown, true we did have to beat them up a time or two, but they have been our best friend and we to them, give or take a few skirmishes for the last 120 years or so.
Only thing holding England together today is the tradition of the Crown, take that away and England will fall.
