Also, the American people are the most polled population on the planet. Business interests have to know what people think, so they can make informed propaganda decisions.

Business interests typically keep these private, and prevent the public from accessing them. In rare instances they are leaked.

For example: The Pentagon Papers revealed that the military leadership was way more pessimistic about the war than the press or the public.

This is part of the impetus for outrage, because the war was going far worse than the public had even imagined.

The story about the cantankerous press, was a myth. They reported the war exactly as they were instructed.
