While I suspect this is a troll post just for fun post, the money is in making the sauerkraut, not in raising cabbages. The beer company makes a lot more than the hops grower and the potato chip company makes a lot more than the potato farmer. There's simply a lot more value added into the finished product for the manufacturer who isn't limited by how many rai he has. He also isn't subject to insects and disease and weather.
