We spend a lot of our time ignoring big problems. It is not a new phenomenon. Many people refused to believe that Hitler held Jews and "social deviants" in concentration death camps. Americans like to conveniently forget the Cherokee Trail of Tears and the displacement of Native Americans in early US history. In modern times, we like to gloss over things like genocide in Darfur, civil war in African countries, poverty in countries like Haiti, and a lack of clean water in many developing countries.
