Earlier quoted context omitted.
In 2003 it reports that small farms that have $10,000 - $249,999 in sales to be 34% of all farms (in 2003), which is still quite significant compared to the 4.8% that industrial complexes (1.7%) and very large family farms (3.1%) hold.
It's not about super large farms, it's about the industrial machine that has taken over small and large farms, in order to receive subsidies and remain competitive. "Small farmers are often absorbed into factory farm operations, acting as contract growers for the industrial facilities." (Wikipedia) These are still considered independent farms in the census I believe. Corn and Soy Beans account for by far the majority…
Have you done this yourself, or are you just trying to score rhetorical points?
I have: my parents are corn/soy/livestock farmers on a small farm they own in the Midwest. Their friends and neighbors are all small operations as well. It's not a job you make much money at, it's true--imagine if all of your income depended on good weather and timing the commodities markets right! They stick with it because it's a job with independence and pride in producing something the world needs. Heritage and tradition, too: many have ancestors who have been farming in the area for a century or more.
It's easy to vilify something if you don't understand it.
