I think it’s tangential, actually and has to do with the usual lack of sophistication in men who earn lower salaries that is the hold up.
You make a good point and I agree, I just don’t usually see it work out IRL and I understand why.
There’s more to being supportive to a high powered mate than keepig house and taking care of kids. These wives of CEOs network a lot, looking for opportunities, schedule stepping stones for career advancements, host parties to make connections, smooth the spouse’s rough edges, cheerlead, calm down, dress him for success, guard, run interference for, research for, advocate for, etc. I could go on. These wives are power ups in the game of Life in any way they can be.
Far more than is ever acknowledged or realized. It’s not just keeping the house and the kids, they’re constantly investing in the husband’s job and career as well.
The stay at home dads I’ve known keep a decent house usually and they take care of the kids adequately. They don’t support their wives' careers. I’ve never known one to host a dinner for her boss to increase chances of getting a promotion, sacrifice for her continuing education, research market opportunities for a presentation, shop for success/power clothing or accessories, that kind of thing.
When you bring up lack of sophistication, there have been plenty of women from simple backgrounds who married up who invested in learning things like how tp set a formal table, which fork to use, the subtleties of floral arrangements, cultural quirks, etc. All the soft skills that work toward showing yourself and your partner as being put together, dependable, excellent, sophisticated, worth trusting and advancing.
When men marry up, they tend to want to chill, do the bare minimum, and play video games. They’re coasting.
I’m not saying there’s anything wrong with that. I am saying that if you are an ambitious woman who wants a high dollar high power career, this guy may not be dead weight, but he’s also not going to be a power up for you, career wise, either.
