One point that Stossel forgot to make. GREED is void of socioeconomic position OR political party. I have no fear of greed for money among individuals as long as the Law punishes those that pursue illegal means in their quest.
The worse form of greed and the form that is ignored by the corrupt leftist media is the greed for POWER. The form of greed that obama and his corrupt leftist plutocrats have. The greed to control and dominate others and to live off of the work of their labor.
Our Constitution is designed to temper this form of greed. But it also takes a free and independent press, and an educated, informed and morally religious people.
