When the press went thought their big 'downsizing' in the 80's they filled in the gaps by taking more information from DNC war rooms, intelligence thugs (disgruntled FBI like Deep Throat) and less from investigavive reporters. The result? They became dependent on the folks feeding them... dependent on folks who could cut them off. Dependent on folks with an ax to grind. Bad toxic incentives for a free press.
Interesting thoughts, and I think accurate. Add to that the ever-trending to the left of the universities training them, you have a propaganda machine.
