I've been mulling this over for some time. I think this argument works pretty well.
I think an argument can be made that is outside the world of commodity prices (I do mention demand which is obviously related). The prices of retail products will be mentioned.
Every bushel of feed/industrial corn that goes to ethanol removes some amount of corn, wheat, or soybeans from the food chain supply. It’s important to consider that all primary grains are impacted by higher corn demand.
This reduction results in a direct reduction in the food supply. Here are some possible examples: less feed corn for meat production, less soybean for tofu production, less wheat for bread production, and less industrial corn for corn sugar production. This is a direct reduction in the amount of food produced.
The United States population is increasing. This means that food demand is increasing over time.
So per capita food production will be decreasing, which will lead to higher food prices. Increased food prices won’t cut individual calories across all income classes. Food price increases directly impact the poor, specifically those living on the margin where “paycheck to paycheck” is barely cutting it and abject poverty is a real possibility (one medical issue away). Volunteer at a food bank to meet these people, they are a wonderful source of inspiration and humility.
Yes, imports could increase to offset the reduction in food supply. Except the United States is the largest corn exporter in the world. So this reduction in supply will impact other countries. Global population is increasing. So the amount of food per capita will decrease through the combination of food sources going to fuel production and increasing population.
Corn exports by country:

Sugar cane and sugar beet ethanol are different stories. But corn based ethanol in the United States is a direct tax on the global poor in the form of higher food prices. It would be different if we weren’t the primary exporter (exporting 4 times as much as the next exporting country).
Frankly I think the equation comes to this: Food based fuel = dead poor people.
How is this not the case?
