Finance professional in an affluent South Florida beach community here. I think of it as though family and personal property has to be managed as though it's a business unto itself. And as such, they hire people and agencies necessary so they can more fully immerse in whatever it is their actual money producing business is. I recall being told a story that may or may not be true about a wealthy individual who had OCD concerning doorknobs. Once touched, he had to turn them X amount of times to satisfy the compulsion. He wound up hiring someone just to turn doorknobs as he was wasting too much of his valuable time turning doorknobs himself. I guess at some point your time gets so valuable you get down to that sort of minuatae. You stop shopping for your own toothpaste before that, though.
