The way to reduce wealth inequity is to allow polygamy from a legal and social point of view. Very wealthy men would have multiple wives and where all their children will be accepted by society which would incentivizes quality women to choose to be one of many wives of very wealth men. In such a situation spending on all these families (wives and children) will dissipate the wealth and shift income downward in the wealth hierarchy toward those providing services for all these extra families.
What an idiotic idea. A large proportion of young men without prospects of marriage is a guaranteed recipe for violence.
