"U. S. corn subsidies amounted to $56.2 billion dollars from 1995-2006."

By showing the total for twelve years, you make it look bigger than it really is. The annual farm subsidy could be expressed as 4.68 billion per year which does not sound out of line.

Odd that free market forces are reviled when that suits some people's political purposes and begged for when that better suits the same person's goals.
