I work with highly educated and successful women (at multiple jobs now).
Most of them do not give a fukk how much their boyfriend makes. The make their own money. They’d laugh at the thought of relying on a man to support them.
It depends what you mean by "successful".
The successful women I'm around definitely want to marry men who are equal or greater than them in status. Now they may date guys who aren't quite up there but their goal for marriage isn't being with a guy who isn't the bread winner.
BTW... I'm not saying you're lying, I'm just saying successful has many different meanings. And in my experience, a successful woman is not settling for less unless she has low self esteem.
Edit: for example... there are some women I know who have a managerial role, their own place, their own car and think that's success. But you add in the student loan, car note, monthly payment for the rent (not mortgage) and you then see how that 50/60 thousand a year before tax, doesn't leave a lot for disposable income.
Then take my friend whose salary is less than that but he owns his place and car debt free. He has passive income from other businesses. On paper.. his hourly rate isn't enough for the woman in the OP... but he has so much disposable income, he is taking vacations every month.
