Exactly.
Rich/powerful men have endless options because they have no problem dating poor, working class, middle class, upper middle class etc.
Rich women don't usually want to be the breadwinner unless they live alone. It's not wired into them to take care of a man financially.
Rich men know this so they can always play 'em against each other. If I was a rich (like $100 million+ ) dude and single, I'd probably date ladies that were college professors, doctors etc. The education aspect is important since the woman is the first teacher of the child.
