Like Steve, I applaud you asking the amount of questions you're asking. Generally speaking, it's not at all annoying, but I will admit that, by the time I read the third of your posts immediately quoted above, I was yelling in my own mind, "Asked. And answered. And answered again. And you even asserted that you understood at one point."
Among the many excellent direct responses that were made before you continued to grind the ax of, "Hey, if he isn't providing enough so that his first wife doesn't have to work outside the home to pay for some of her own food, clothing, etc., how can a man justify having an additional wife?", perhaps Steve's was most to the point:
This, to me, is a heart thing. It's natural to look out for oneself before jumping into a situation, but it also demonstrates a certain lack of faith in Yah's Wisdom to over-worry about whether one is going to be taken advantage of.
@frederick pointed out that this discussion is also in need of making the distinction between wants and needs. The biblical admonition in Exodus 21:10 simply makes clear that the buck stops at the 'desk' of the husband. It doesn't mean that the husband is responsible for every aspect of the sweat equity necessary to ensure that everyone in his care receives their share of their basic
needs; he has every right, in fact, he has the
responsibility to delegate so that everything will operate most efficiently, most humanely, most effectively -- and what is promised is food, clothing, protection from dangers and the elements, and due benevolence. There's nothing in there about smartphones, social media, trips to the museums, or any kind of generalized grins and giggles. Much less 401Ks.
I and others have written elsewhere at length about the tendency, in the discussion of polygyny as a theoretical matter, for people to start having unnecessarily highly elevated expectations for husbands who want to be husbands of multiple wives. This is a snare of the highest order, because where it goes is in the direction of first wives becoming increasingly 'entitled' to have one of the best husbands, and for potential second wives to have the misguided expectation that, if they're going to be willing to engage in that family structure, they also have the right to expect their future husband to be a better man than the average monogamy-only husband. This is sophistry.
I know it's sobering, but sometimes -- even though these start off with great questions -- discussions such as these need to be grounded in what is real. It's only a fantasy that most of the unmarried women are choosing from among a smorgasbord of potential Prince Charmings. In point of fact, we're talking about women who lack covering, which also means they lack protection, they lack companionship, they lack sexual intimacy, and they lack any real sense of security. If they're not on welfare, they have jobs, and they are living their lives day-by-day just like everyone else, but without stability and generally immersed in loneliness (which itself is a silent killer).
So it's all well and good to say that a man shouldn't seek a second wife until he's got all of his ducks in a row, but what I always notice that we leave out of the equation is that, if he's only a mediocre husband like the average monogamy-only husband, and he may end up requiring his first wife to cut back on the Louis Vuitton or the hair salon or having complete access to her own automobile in order to take in a second woman, we have the tendency to either (a) focus on the fact that the first wife may have to sacrifice [not needs, but wants] or (b) focus on the fact that the hypothetical incoming second wife won't be living the life of Reilley. In reality, what is really happening on the ground is that, if that guy doesn't offer that potential second wife slot because he's influenced by our misplaced negative judgments, the end result is going to be
just another lonely woman left out in the cold. What about
her? Is
she really better off all alone than she would have been in a family where she might still be asked to work part-time at Walmart? And is her entrapment in loneliness unworthy of asking a first wife to wait longer to get a new purse?
