A very informative read is to be found in the New York Review of June 7 2012 (www.nybooks.com. 2012/06/07).
In this, the reviewer (Jared Diamond) examines the work of Daron Acemoglu and James A. Robinson “Why Nations Fail: The Origins of Power, Prosperity and Poverty.” The authors are very much of the opinion that these differences in wealth distribution, country by country, are solely the result of good or bad “institutions”.
As the reviewer goes on to show, however, when it comes to the question of why nations differ in wealth, “The factors are multiple and diverse”. There is certainly no “silver bullet”! The one advocated by the OP would only serve to drag everybody down to the same level of poverty.
(I have witnessed this in Papua New Guinea, where the traditional “Wantok” system, when used in a modern industrial society, only serves to impoverish everybody).
