OK! Well, where to begin. The blurb that got me to read the whole article was this one, quoted from the State Department website (click on 'economic'):
Economic conspiracy theories are often based on the false, but popular, idea that powerful individuals are motivated overwhelmingly by their desire for wealth, rather than the wide variety of human motivations we all experience. (This one-dimensional, cartoonish view of human nature is at the heart of Marxist ideology, which once held hundreds of millions under its sway.)
