If the law was even handed and eliminated alimony all together, or in all cases of infidelity, sure that would be fine, but it didn't do that. It specifically called out women.

That said, if you're divorcing and suing for half of your joint possessions, you could make a strong argument that the years of support you gave your spouse entitles you to a portion of their income until you marry again because without you and your support they would not have been able to achieve as much, especially if you became a stay-at-home spouse or parent to allow them to work.
