Capitalism is the pure profit motive, and is an obvious threat to everything.
Every single crime in the world is due to the corrupt motivation of capitalism.
It is true capitalism is the most powerful motivator, so is responsible for our wealth, but is also responsoble for the down fall of all previous most wealthy societies.
