From the studies I've seen, most men are financially as well off within 2 years of divorce as they were before, whereas most women at significantly behind where they were for a decade or more after divorce - and that's after getting the house and the kids.
Most 'stay-at-home-moms' have no retirement savings, they aren't qualified for well paying jobs, they still have the upkeep on the house and kids to cover, the support payments men complain about so often generally don't cover 100% of those costs (I'm not saying it should).
People don't get divorced for the fun of it and it is extremely rarely for financial gain. Sure, we see the odd story of some super wealthy guy who marries a gold digger who takes him for millions - but that's not the norm.
That's like people who think teenagers get pregnant for the increase in benefit payments - the costs generally exceed any increase in welfare payment - it's not a profit making option.
Marriage should be like a tattoo - don't get one unless you plan to keep it forever. But if you really need to, there should be an option for getting rid of it. It's better than going through the rest of your days miserable.
