snowmama - but that kind of arrangement could apply to HM relationships as well, but allow other people the same kind of security, without having to be married to achieve it.
people can choose to declare 'we are a family' define who it consists of & how they will contribute, and also define how they will divide assets if/when the family unit changes/ends.
so a married couple could do all that, and redefine the situation once kids are grown. a gay couple could do it, just friends who choose to live together & raise a family, 2 sisters could do that.
if there were some security to it, it might encourage more stable relationships but without limiting that to only one kind of 'family' as defined by society/tradition.
i think that for some, not all, families, the option of having one parent stay at home for a while is a good one to have. the early years with kids is vv tiring, and if they need time more than money, then they should be able to pool their resources if that works for them. however, finances are heading towards every one being reliant upon themselves. there are many positives to that, but it does rather imply that all adults work all their lives, unless vv rich. which actually starts making it harder for some people.
i would just like to see some more flexibility and choice for the individuals without feeling trapped into a certain model, which may well not be the best one for them.
