"Take out regulations and you wouldn't even know corn was in the product."

This makes the assumption that consumers are stupid, have no standards, and will buy anything regardless. I don't believe that for a second. On the other hand, government regulation often carries with it unintended consequences. For example, insurance companies recently predicted premium increases of 100 - 400% as a result of the still not fully implemented ACA that was supposedly intended to make medical insurance MORE affordable. There are many examples where the government stepped in to cure a problem with regulation, and ended up creating more problems. A study done not long ago indicated that The Great Depression was prolonged by approximately seven (7) years due to New Deal policies. Organized crime during the mid twentieth century was funded from black market sales due to government prohibition of alcohol. Todays war on drugs is doing essentially the same. Government CAFE standards mean lighter, smaller cars full of plastic and less safe during an accident.
