That rich guy in your example probably values price discrimination just as much as you do, because he - presumably not being a cheapskate - can just pay more and know that all the conveniences he wants will be there for him. And then he goes back to thinking about his next genius business plan, because it's not worth his time looking for the best bargain. So both win.

The reverence that people has for rich people astonishes me. Rich people is just average people with money. Actually, they are probably worse at their jobs because they need less effort to earn money.
Rich people are not rich because they are "genius" but because they game the system.
