Are speculators' destroying Global economic recovery?

On a range of commodities; we just see prices going up and up and up. Just today the Gov't along with other non-opec nations tap into oil reserves which really did not have much of an affect on lowering light crude ( now trading at $95). If Conservatives really want to help America then please stop focusing only on Taxes and help put a stop to speculators! moreover; why not go after them and make a difference instead of a one-sided approach to fixing the economy or 0bama being a Muslim?
