My family just spent the weekend in Iowa. We have roots there and we reap a small windfall from all the corn we saw growing in the fields. Its heavily subsidized to the tune of $50 billion. Its also making Americans fatter and we will pay a heavy price for these subsidies as we also pay to treat more people for medical ailments related to obesity. It would be ironic if the best way to keep corn syrup from adding to our girth would be to pay to have Americans stomachs stapled.
For a little more detailed explanation of the problem look at this short post.
