Not true at all. Not many evils result fom any one in particular source. Evils exist where people are broke and where they are rich, aswell as in between. Life in general is the cause of 'evil'. The things that people expereance in their life, the circumstances they face, the way they are raised, and their inability to deal with these things are what causes evil.

One of my favorite quotes is by Edmund Burke "All that is necessary for the triumph of evil is that GOOD men do NOTHING"
