Agreed. My most comfortable client with a number of yachts, properties all over the the place and x zillion in the bank drives an old car as a run around, uses Thomson airlines from his local airport when he can, and tho' he will pay his way, would not dream of subsidising others one iota, yet anonymously (almost) gives his funds and time to Charity, too.
If he has flown First class he has never spoken about it.
