I challenge - continually - the value set that assumes the world needs such arbitrary (universal) goals as "middle income status" in other to be "acceptable" in the league of nations. I would instead argue that "successful" societies are those that evolve intellectually and culturally - as well as with heightened technology, infrastructure and density. In such an evolved society the citizens could aspire to an urban / rural ; industry / agriculture mix that they strive to develop and maintain at a level of need - i.e. continuity / sustainability. That, to my mind, is a far better scenario than a "middle income status" - with its assumed Western delights.
