What do you make of dowries, where the bride's family transfers wealth to the groom's family? Are they buying the sex of the groom? This would be consistent with what you are saying. Dowries (wealth from bride's family to groom's family) are much more common today and throughout history than a dower (the reverse wealth transfer).
