This is not how it works. People going hungry in spite of their country having a good crop is a sadly regular theme throughout history. Crops going to the highest bidder and crops going to whoever has the most political influence are sadly regular occurrences. (the most recent example of relatively widespread hunger of this sort that I'm aware of occurred in the aftermath of the 2008 recession, although economics isn't really my thing)
