It seems more "Hollywood horror" than reality to think there could exist a handful of companies some privately owned with so much power, wealth, and political influence that they could run, better yet manipulate this countries... the world's food industry for their own financial gain, but it's true!
Cargil is the largest privately held corporation on the planet and they account for much of the global grain trade. They are one of about 6 companies that control nearly 75% of the grain handling facilities; they flood the market, they manipulate price, and they profit. The U.S. produces tens of billions of bushels of corn a year, half of which is exported and most of which is used for animal feed (cows, chickens, pigs, fish, etc.), and Cargil is one of maybe 3 companies that control over %80 of the corn being exporting. But their rule doesn't stop there, they are one of about 4 companies that control over 80% of the beef packing industry. Add to that ties into pharmaceutical and chemical companies as well as the oil industry, and it's easy to see that they are an agri-conglomerate with world domination on their minds.
Together with the likes of Monsanto, ConAgra, ADM and our government they will continue to dominate global control over what is produced, how it's produced, and how it's used, all for their own profit gain and our loss.
