Polygamy is still tolerated in most countries – the problem is very few men can afford it. With the economy favoring women (at least at present – it’s not clear that’s true with AI eviscerating administrative jobs) the cost of a ‘stable’ of women is radically reduced. Yet for women, the benefit of sharing a household and man with other women, lowering the cost of each woman’s participation in the household and in maintaining the man, is decreasing. So we are left once again with intersexual relations that are in a hierarchy from permanent to temporary, to fractional.
The incentive to marry was a produce of agrarianism+herding and the incentive to marry today, in the current economy isn’t really more than just the cost of household income vs individual income.
