Agree with what you say. But your job, however hard it might be, is more palatable when you have people at your call and when you’re insanely rich. Contrast this with the lady at CVS near my home - she is at least in her 70s, looks frail and tired all the time. It is sad that she has to work at her age.
Money doesn’t solve all problems. It sure makes them less horrible though.
All that said, the queen was an impressive human. 70 years is a long time. I’d be bored in 3 years and quit
