The cry speculation is a political agenda and if a US politician thinks US futures traders can control the world market they are nuts. Many countries have tried to control futures and none successfully. In the 1400's during the Japanese rice famine the govt. accused the traders of futures speculation took control of the market and distribution and successfully starved 14 million people.
I might have read your post on that. I think I also heard it mentioned on the Fox Business show block on a Saturday morning. Maybe they read your posts too;-)
