Never underestimate the power of the public's stupidity.
Recently there was a drive to ban a certain chemical - it had found it's way into our tears even. When the chemical name was changed to what it really was -- people were signing a petition to ban water.
A legislator in (I think) Ohio at one time wanted to pass a law rounding pi to 3.14. Another wanted to pass a law to increase education spending so all children would "be above average" in test scores (freaking duh, just freaking duh).
You can fool all of the people some of the time - and make them look like morons as you do it. Bernie Madoff did quite well, just didn't know when it was time to cut and run.
What is frightening is, these people passing laws think they are doing good things.
