In Ethiopia they are starting with advanced agriculture, and the World Bank is critical in jump starting that process. Foreign companies need to participate in a local economy when there are no local alternatives.
The people don't get the food produced on their farms because they can't afford the food. They can't afford it because the Ethiopian economy is in its infancy. Sure it doesn't feel right when the food is being shipped out of the country, but that's how capitalism works.
If Ethiopia plays by the rules of the game for the next few decades then their economy will grow the problems we see in today's Ethiopia will be diminished.
Starting this process is the purpose of the World Bank.
