But every one is a potential father or mother. I guess another solution would be to require employees to put up a bond that covers the companies expenses in case they go on absence. The cost of a risk of absence has to be paid by out of the gross salary anyway, so we might as well make it more explicit.
(I do not know whether you could then put up a (possibly subsidisied) insurance company to cover the bonds in case of having children. The problem is, that having children does not work like accidents or fire.)
Not really. It's a sliding scale, but at some age the "new child probability" drops dramatically. People who already have children over a certain age are unlikely to have more children too.
That will probably just extend the effect to potential fathers as well. It's probably a "you just can't win" situation :-/
