re: Farming and seeds
Capitalism indeed at its finest. You see, the seeds you buy from the corporations work one hell of a lot better, germinate better, create higher yields, need less fertilizer and pesticides (some need NO pesticides) and make the farmer a hell of a lot more money that stuff he would breed on his own. There are many competing seed companies vying for the farmer's business.
You might note that absolutely nothing prevents a farmer from using ordinary grow-it-yourself seeds, just like nobody keeps you from weaving your own cloth for your clothes.
