Edit: my mother had me checked - I am not insane. Anyway: while you are right that keeping two unhappy people together might be much worse than them splitting up, I can imagine that a big organisation like the church (any church) will be a force opposing this idea once they figure this one out.
Might as well make divorce illegal again. After all, something nicer might come along.
If the only thing holding your marriage together is needing to pay the bills or a judge, being forced to stay together only serves to make people like you feel righteous.
Your comment makes me wonder about what other unhealthy ideas about relationships you want to force upon others. Perhaps you should spend less time on r/MRAs and r/TheRedPill.
> So with everyone getting free money, including the children, there is no need for a father to take care of the family when he decides to diforce, right?
Having to pay child care costs and alimony above the poverty line are things that exist now and will have reason to exist even if a BI is implemented.
Is a family that's only together for the money worth keeping around?
It certainly would mitigate the social harms caused by deadbeat abandoning parents, but since neither child support nor alimony are currently limited to the amount necessary to provide basic survival necessities, a UBI mature enough to provide basic necessities would not seem to be a basis for eliminating existing child support and alimony provisions.
Obviously, even with existing formulas, the fact that more of the family's income wouldn't be leaving with the prime breadwinner would reduce the amount of support and alimony orders.
> So marriage will no longer be a bond forever
Marriage, in the US, is only a "bond forever" now to the extent that the parties decide to make it one; divorce is readily available, and frequently chosen.
Honestly, I'd rather see families split up, if by "split up" you mean "find independence from someone with whom you do not want to spend your life". There's levels here- children are a responsibility that someone needs to shoulder (and emphatically not just Mom), but if the alternative right now is being trapped economically in an emotionally traumatic relationship, that's not good either.
