You are describing people who are rich because they and their lineage belong to professions. That's a kind of modern aristocracy, and like most aristocracies they have good manners and obey a kind of noblesse oblige.

But also, most of the unequal laws and policies in a country are created to prop up the position of such people. E.g. house-price inflation helps only those who already own - or stand to inherit - houses.
