Well...they make profits by selling more seeds and seed corn than the next guy right? and what is the best way to sell more seed than the next guy???...thats right its by producing a better product. Thus, all the seed manufacturers are in competition with eachother to make the best seed and in turn make more money. And the consumers benefit from it because we are eating and fueling our cars with the best corn and we benefit because due to the competition and diversity we dont have to worry as much about possible diseases and stuff that might hit the corn.
