Barack Obama: (Elko, Nevada, September 17, 2008) I believe that our free market has been the engine of America's great progress. It's a market that has created a prosperity that is the envy of the world, and rewarded the innovators and risk-takers who have made America a beacon of science, and technology, and discovery. But the American economy has worked in large part because we have guided the market's invisible hand with a higher principle - that America prospers when all Americans can prosper. That's why we've put in place rules of the road to make competition fair, and open, and honest. Our capital markets cannot succeed without the public's trust. It's time to get serious about regulatory oversight, and that's what I will do as President.
