This social construct only works for highly successful men that are at the very top of the food chain which accounts for a very small percentage of men.
Women get older and are more willing to settle and they will share a highly successful man willingly, but some more average breh that works a 9-5 that she’s splitting bills with better not even think of trying this shyt.
Your worth is based on 3 things…
How hard you are to replace
What you bring to the table as far as attributes
How much revenue (money) or social equity (who you know) you bring
All conditional arrangements revolve around those abovementioned factors.
Based on that all men are not made equal and her level of submission and compliance will revolve around those factors as well her emotions and where she is at in that given point in her life.
I'll also take it a step further
The other scenario where it works is in a relatively small (few hundred to thousands) society where fiat currency is not the means of survival, essentially a rural one where the people are self sufficient and families are very close and the cost of living comes down to resource management of the environment.
Because in that situation, the men just have to worry about building the living infrastructure and acquiring the food, women essentially supporting that by cooking the food and maintaining the infrastructure (along with other things on both sides like weaving clothes and crafting tools for example). A simple life like that means child bearing and rearing is a relatively simple matter.
To add to that, there still has to be a high level of respect and appreciation on both sides and strict societal guidelines for participants so that nobody blows up the spot so to speak.
But you know funny thing is a man doesn't have to be highly successful in that scenario. Cause let's say he got two wives and they all worked full time jobs. If they each made like 20$ an hour that's 9600 dollars a month, sacrifice doing that for like two years living below their means and they could save some serious cash but most people these days are just too focused on optics to ever discipline themselves that way
