That's why the ole "But why should I pay for her dinner? What does she bring to the table?" question is so... underwhelming.

She brings to the table the social status required to be able to expect someone to value her company enough that he's willing to pay just to have her undivided attention for a couple of hours, at the same time that she possess the financial stability to not need the money he pays and the options to choose who gets the privilege to pay. That is something very concrete that can work to his advantage, later. And the more men would be willing to pay for that attention, and the more each man would be willing to pay, the more of an advantage she brings.

Men will pay, just to speak to her and watch her chew food. They will buy her an $80 steak, just to watch her eat it. She might even regularly turn down steak dinner offers. She might even be turning down gold-dusted steak dinners in private jets on the way to Malibu offers.

This is someone you want on your team.
