What is the overall message presented in this quote? "Much of the blame heaped on the captains of industry in the late 19th century is unwarranted. Although people like Rockefeller used methods that were ethically questionable, the kind of monopolistic control that the exercised was a natural response to the cutthroat competition of the period and reflected the trend toward business consolidation in all industrial nations. The captains of industry like Rockefeller who were innovators, thinkers, planners, and bold entrepreneurs who imposed upon American industry a more rational and efficient pattern. They also created a model of philanthropy for all to follow. Had it not been for these captains of industry, the free world might have lost the first world war, and most certainly have lost the second.”
