there's no grain shortage in any of the countries mentioned, there's shortages in africa and the developing world, and the above mentioned countries farmers would rather not foot the bill in reduced grain prices, so the developing world can be fed while they starve, they would rather the rich eu nations pay them to allow grain to move through their countries, which is fair by anyone's estimation. it's all in the matter of who pays the bill, and how many africans the world feels should eat at any given time. it's all money, the infrastructure is there for transport. it works fine.
