interesting find

I found this on Wikipedia while looking for a book on urban weeds, re Prof Lewontin of Harvard University:

Lewontin has also written on the economics of agribusiness. He has contended that hybrid corn was developed and propagated not because of its superior quality, but because it allowed agribusiness corporations to force farmers to buy new seed each year rather than plant seed produced by their previous crop of corn. Lewontin testified in an unsuccessful suit in California challenging the state's financing of research to develop automatic tomato pickers, favoring the profits of agribusiness over the employment of farm workers.
