Rick makes a good point. Star power is a big thing. Just look at how much money governments are willing to pay the likes of Tiger Woods just to appear in a golf tournament. All royal appearances are done for free. I for one do not envy their lifestyle. Under the public microscope 24 hours a day. Even Liz is a tireless worker, now at 81 years of age. Like they say. "It is a job that thay did not choose, and it is for life".
