Here is a column about John Edwards, whose presidential campaign is faltering. It must kill him that his message of envy and resentment isn’t catching on. But why should it? This is the land of opportunity. Americans are hopeful, not envious. They admire those who have more money than they do and want to emulate their success. Edwards would be a hit in Europe, where envy is a way of life. He has no chance in the United States.
