Men want the woman more in need. Men are not impressed by her income.
Some men want that. Not all though.
I'm not implying that men are impressed by her income. But again, there are men out there who don't want to foot the bill for a woman on a long term basis and want something where they aren't expected to be the sole financial provider.
This isn't the 1950s where women can stay at home and the men pay for the house, car, food etc etc. At least not in Canada, the US, and several other countries across the world.
Not every guy wants that stress.
Also, that concept feeds into the hypergamy theory of women's dating/ mate finding behaviour, so you have a situation where there's an expectation on your part to provide for the woman in need, and in return she provides xyz. Well in an economy where the cost of living keeps going up, people get laid off, lose money on investment stock, get sick and can't work etc etc, how comforting is it to have what could essentially be just a conditional arrangement with a woman who will dump you asap the moment something happens in your life and you can no longer provide for her needs?
I think when a guy sells himself as the 'provider', he's likely to attract the kind of women who will use him as long as he is providing and will ditch him when he can no longer do that and/ or a better provider comes along. Hypergamy.
There needs to be more than that, for something long term anyway.
