Goal: Land Management
Billionaires or a foreign country buys up land for their own use or control. Gates wants to control the food supply so buys up farmland all over. Maybe he will rent the land back to another farmer or corportate farm or just lets it set to go wild. China has bought a good deal of land, and since they have a difficult time feeding their people, they could have farm workers grow crops, harvest them and send the grain back to China to feed their people, and let American barely make it by.
