So you're arguing that, even though he signed a contract (yes, marriage is a legal contract, and you shouldn't sign it if you don't agree with the terms), he should be able to back out of it, because of some general dislike for "the womens lib movement"? If he wanted to sign a different contract, he could've asked for a prenuptial agreement (which is common among the wealthy), or not gotten married. But he didn't; he signed the contract, so now he should honor it according to the terms he agreed to, and any attempt to weasel out of them is duplicitous bullshit. Should PayPal be able to back out of its contract with him post-IPO, and decide that it didn't want to give him that much money after all, because he didn't "deserve" it?

And yes, I do think moral support plus raising five of your children is sufficient support to deserve half the money you made in that period. If he thought otherwise, he shouldn't have signed a contract saying so. Since he did, the only honorable thing to do is to honor his obligations, not the current pathetic show he's making of trying to claw his way out of them after the fact.
