ok, i haven't read this all, BUT
if the idea of separation, is to make men realise how much women do, and then to start to value them, why are we discussing women raising children?
haven't feminists seen that as one of the main stumbling blocks towards equality? that someone needs to look after children, and women tend to do it, which impacts on their ability to work, and makes them reliant upon a man.
well, could women separate from men in such a way that they only meet with men for mating, then they care for the child for the first year, after which the men have to raise them?
this is, of course, only a theory, not in the least bit practical, but you would end up with 2 societies - one where women have to allow for maternity leave and raising a baby, the other where men have to structure their society to allow for child rearing. i wonder which one would end up being the more profitable? if both groups were able to trade, then would the society where profit is affected by maternity cover suffer economically, or the one where childcare had to be accounted for?
i strongly suspect that the women's society would be more profitable, if all other variables were equal. which kind of shows how much society, (both small scale families, and larger, country-wide societies) benefit from the free labour of women.
