I have not farmed since 1972 and until a few years ago corn was about the same price as it was in 1972 no way has it kept up with inflation. Farmers are getting more yied but they can not keep being a cheap bread basket forever. as for the fuel I agree we can use grass straw corn stalks but we can also use all the corn going to feed livestock and take the alcohol out of it before we feed it. All it will cost you is the price of the process.
