the economy today is credit like economy. (borrow and spend)
developing countries (3rd world) to ensure employment, push up productions, and then lend $ to developed countries and wish them to spend/ use as many finished goods they manufactured. the 3rd world will continue to exploit their natural resources, commodities to create enough $ to lend to the developed nations.  the music will go on until no more resources/commodities to continue the cycle..

when 3rd world dried up and no more resources/$ to lend, developed nations will stop consuming, unemployment in 3rd world will increased. riot begin and war started. developed nations will then rule again. so it is better than old days where 1st world conquer/colonize the 3rd world and steal their resources and slaved their ppl.  They use a new way to slave the 3rd world.  (north korea is smarter they build nuclear weapons not commodities)
