> Modern farmers are as productive as 10,000 peasants.
I realize you're exaggerating, but it seems like the real number is more like 10x, and cannot be much more than 120x: http://www.ofac.org/issues/faqs.php
> On average, one average farmer feeds over 120 people today compared to 1900 when one farmer fed about 12 people.
I think you forgot the fact that we eat food that takes much more work to grow. if we will return to eating mostly rice and beans(like in india for example) - the work in those fields can be highly automated , and i'm pretty sure a farmer can feed a lot more than 120X people with rice and beans.
