What the quote doesn't mention is that Quigley states only a little while later in his book that he thought Financial Capitalism failed. Quigley is an interesting and provocative writer, but his book, IMO, does not treat the greedheads as the controllers of the economic patterns he describes. In his description, they are only 'along for the ride', taking advantage wherever they find it, instead of being the primary motivating factors for these events. He attributes the economic effects he describes more to human nature in general than to the greed of powerful individuals.
