People are stupid; it's proven every day by people who spend more on junk than the necessities, and end up paying high interest rates on their credit cards. People go into debt, and can't make their payments. People vote for the dumbest candidates, because they love one-liners that seems to make sense, but doesn't have any depth of understanding or thought.
Look who we elect as our government representatives; they fight for their political cause forgetting that they are there to work for the people, and to improve our lives. They prefer war over building up our infrastructure, and taking care of our own who have lost jobs and homes. Our country is involved in three wars; Libya is costing the American taxpayer $10 million every day while we cut funding for our schools, our police, and fire departments.
It's a crazy world, because people are stupid!
