Who is "screwing with the world economy and food supply?"

What has the U. S. done about the oil and grain futures market other than complain a bit? A lot of speculators have made fortunes. Some may even pay a few taxes on their gains. But they are contributing to starvation and turmoil.
Neither McCain nor Obama say much about this.

Now who is "screwing with the world economy and food supply?" The U. S. as usual, stinks in this regard as much or more than "the oil producing nations."
Canada is the largest supplier of oil and natural gas to the United States. Finally, it is getting a little of its own back in that regard.

End of rant.
