I'm not sure how it works in the USA but here in Canada (and I only know this from taking a course recently) it is very much even now. Alimony and/or child support is decided based on the incomes of the two individuals regardless of the sex. It matters not one way or the other which was the main "bread winner". The courts only view it as what is best for the children of the marriage and to make it fair for both parties. Sure...there are still lots and lots and lots of money-lusting divorce lawyers out there who will scream SUE!. But that just isn't the way it has to be.
You don't have to go to divorce court and battle it out the way everyone envisions it through tv and their friend's horror stories. You can go to a mediator (which in most cases is actually FREE) where you work out every single detail....the only lawyer action you see is to pay them to finalize the signing. No billion dollar lawsuits....no scrabbling over access/custody.
Sorry...off topic here but what I can tell you is that the courts now don't look at "sex" as the deciding factor at all. Men and women (in this respect at least) are equal now. About time, too, if you ask me!
