Globalized way of Exploitation

Don't know why we always get attracted to the light, i mean why we always in the practice of serving people on the basis of their riches, seldom thinks of the oppressed. Africa, the most poorest continent of the world suffering from hunger, epidemical diseases, poor governance. tribal wars and much more. Earlier this continent was exploited in the hands of European colonial powers, and now it's the turn of MNCs.
Africa, the continent having vast source of resources having the capability of transforming into a developing world on its own.But the ground realities are on the contrary. Hunger, the reason behind most of the deaths in african nations. MNCs of gulf countries as well as of other developed nations, instead of helping in the cause doing the reverse by involving in the land deals in africa. Some of the most fertile lands of Ethiopia , Zambia and others are sold to these MNCs on a lease of 99 years by their respective govt. and that's too at a "blue" price.
And what these MNCs are doing is that they are growing high quality crops and vegetables using some of the most advanced techniques on african lands and export them to concupiscent world of Saudi Arabia and other gulf nations sitting on rich oil resources, playing dirty game with the world economy and preserving their land for the future. It's true that this sort of business provide jobs to the african people and money to their governments. But what to say in case of chinese MNCs who even bring home workers along with them. Overall, the benefits are only for a short term but in the long term this sort of business is going to prove fatal for the future of Africa as well as to the global human health.
