If I earn 300k a year maybe I can pay for club membership (if they let me in) but I would in no way have comparable wealth to members that were going to inherit 100M from their families. You're very focused on income, but people in the upper classes are not. In fact, high earning professions are often looked down upon because when you have family money, it's seen as gauche to work hard for what would be scraps compared to the real family fortune.
