But, this doesn't take into account the critical beneficiaries of this, which are the children, who get a stable environment and material and emotional support from both parents. The point is that a man who violates his marriage vows will be seen as a cad (another anachronism), who is siring progeny without concern for their material well-being, while a woman who violates her vows is seen as bringing in another man's issue, to be cared for by fraud.
In other words, it is economic, but the economics are based on the very real differences between the genders.
