We'd have to change the structure of society. Its a class structure, and there's only so much room at the top. The wealth of the upper class comes from extracting rents from the lower class. This happens on a global scale (core countries exploiting the periphery) as well as a local scale (landlords with good credit collect more in rent than they pay on the mortgage).
If this were true, then when the colonists from "core" countries left a colonized area, then that area should have seen an increase in wealth because those rent monies would have remained in the colony. The history of numerous areas, such as Haiti, Kinshasa, and Zimbabwe say that this did not happen.
The wealth of the upper class comes from courage, determination, intelligence, organization, and productive use of time.
Furthermore, following your rule, Mark Zuckerberg, who is formerly a long time renter, should be less rich than his former landlords.
Actually, according to Wikipedia, Haiti paid off their debt to France that resulted from the Haitian Revolution in 1883: http://en.wikipedia.org/wiki/External_debt_of_Haiti.
Free of their French "landlords" the Haitian "renters" should have seen increasing prosperity since they were sitting on one of the most agriculturally productive (in terms of sale price for crops grown, not total amount of all products grown) regions of the New World. So, what went wrong?
