If you divorce a hard working woman has a history of bringing home paychecks you don’t have to pay alimony. If you are a rich guy and divorce a woman who sits on her ass while the maid does all of the work you pay alimony.
If the ex was keeping the home while the other was building the career, then the ex deserves a share in the gains, but not all of it.
If the ex is a second spouse who married into the wealth, then they should only get a share of the gains accrued during the marriage, not a claim to the whole estate.
