But it is the difference.
only in the case where there are kids does it seem out of balance. Divorce with no children, or near-adult children, or even divorce between reasonable people does not go so badly as the horror stories here. If you have little kids... Divorce should be a painful thing. And I think it should be equally painful for both parties.
It's rarely as painful for the woman as it is for the man. On top of the pain of the actual divorce, the man will most likely lose the kids, get kicked out of his own house and be forced to pay money to the hateful harpy who ruined his life.
In a situation like that, the best thing for a man to do is change his name and move to some island in the Carribean.
