A Question of Support

I've met with a variety of sometimes surprising responses when I tell people that my ex-h has to pay spousal support. They range from well shouldn't you just go out and work to revenge scenarios like taking him for all he's worth. First of all, I am working, I just don't pull down a huge salary. And secondly, I've never been a gouger, and revenge only backfires on the perpetrator.

So here's the scoop on spousal support:
1) women post-divorce experience a 50% decline in living standards within 5 years; while men, post divorce, experience a 50% increase.
2) within five years, 75% of men are remarried, while 75% of women are not.
3) 90% of children living in poverty are living with single mothers.

Those are the reasons why the laws have changed so that women don't need to live in poverty.

I've proposed waiving spousal in exchange for his equity in the house. (He won't be left penniless either since he gets all the retirement funds.) This provides me with the security of a home for me and my children.

More research (acquired by me):

Once men remarry, they cleave to the new woman, and HER children, often leaving his own children out in terms of time, energy, and MONEY. In fact, more often than not, when a man dies, he leaves his estate to his new wife, and her children, and leaves his own children little or nothing. (I personally know of four instances of this, and my lawyer says he's seen plenty of cases that support this.)

And finally, since splitting, his ardour toward having the children has cooled a little, passing up offers of taking them here, or there, or visiting in the middle of summer camp... And so the bulk of t he child care rests on my shoulders. Not that I mind. In fact, I often sit up in the middle of it all, dishes, laundry, signing school forms, overseeing homework, and realize: I got the best deal!!!! But it does leave me with more of the workload.

That said, I realize plenty of men are impoverished paying spousal to an ex who won't work. And plenty of men (usually the ones who didn't walk away) are more than eager to have their kids as much as possible.

So my question is:
is spousal support fair?
