If you were being paid more money to grow beets on land that could support soybeans, why wouldn't you grow beets? It's economically rational to the farmer who's getting subsidies -- even though it's economically irrational for the world as a whole. Subsidies distort the market, and produce completely illogical results. You can't get rid of just one subsidy, because that just gives an advantage to the next-most-subsidized item. But remove all the subsidies, and things will return to an economically-rational state of affairs.
