Saudi Arabia, trying to provide incentives for grain growing, uses expensive sources of water so agriculture isn't really competitive unless with a subsidy. To help the grain growers, Saudi Arabia's government jacked up the price of grain to artificially high levels. The corrupt officials in Somalia seized the opportunity. So much for unintelligent and improperly planned foreign aid. Food production is not the problem.
Distribution is the problem.
All big US corporations HAVE BEEN nationalized. There is no longer any cause for hunger.
