::::::::Sub-Saharan Africa is a good point. There is a big difference between Sub-Saharan Africa and countries like India and China. Wherein Sub-Saharan Africa, there is no local industry that can provide products for cheap rates. Whatever comes to this poverty stricken county is from the developed world. Whereas in India and China, the products come cheap, the labor is cheap and the services are also cheap or even free in some cases (village life). This is the difference between the $1 in Sub-saharan africa and the $1 in India or China. For China to eliminate poverty, it may take another 8 years and for India another 15 years, if we compare the reduction of 1%/year (According to U.N figure) of poverty reduction.
