What about people who choose to have one person stay home for twenty years and spend all their time and energy raising the children? Then the guy leaves and she is older with no way to get hired????
If you want to make the case that in the divorce settlement there should be some ability to split the assets non-evenly so as to compensate for special circumstances (for example, giving a wife who stayed home with the kids 80% instead of 50% of the assets to compensate for her loss of marketability) then that might be a decent argument. Maybe even a period of, say, five years where she receives training while he pays a stipend. But saying that as long as he lives, he is her wage slave doesn't seem fair. I'm sorry, I know many will never see it that way. All I can say is this is our current legal system and men are avoiding marriage because, in part, they know it's a one-sided deal, legally speaking.
