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.

If the law would punish divorce instead of rewarding it, or creating a "winner" and a "loser" in every divorce, there would be less of it.
