But as you say, they’re attracted to them. There’s this myth that women dating notably older men are in it for the money alone - ‘so what is it that first attracted to the multimillionaire pensioner’ - but there are plenty of examples of independently wealthy / successful women who STILL go after the old boy over the young up and comer. Princess Diana’s niece is a good example - girl looks like a model, and she’s married to a 60 something who’s probably less wealthy than her family is.
I wouldn’t underestimate the impact a good looking man can have - a lot of these guys keep it tight, but others probably have an arrangement (the ones dating the clearly ugly older guys).
