It might be a very difficult question to answer, but you could look at it differently. In looking at the grains sector, if you go back a few years--three or four years--it wasn't that profitable. But it came up. If you look at the hog sector, there were different reasons the prices stayed low. You talked about the H1N1 and every problem possible; maybe there should be a study of each one.
Farms usually go from generation to generation, so I think there should be something much longer term than the three or four years.
You may also have to look at the regional economy. What does a farm bring to your rural economy? I think it makes much more return than what it costs the government, to start with, anyway.
