Upton Sinclair explained it best:
“It is difficult to get a man to understand something, when his salary depends on his not understanding it.”
This applies to the mass media, the White House staff, Democratic members of Congress etc etc etc.
“It is difficult to get a man to understand something, when his salary depends on his not understanding it.”
From “Citizen Kane”:
Jedediah Leland: Bernstein, Bernstein, these men who were with the Chronicle, weren’t they just as devoted to the Chronicle policies as they are now to our policies?
Mr. Bernstein: Sure they are just like anybody else. They got work to do, they do it. Only they happen to be the best men in the business.
Jedediah Leland: Do we stand for the same things the Chronicle stands for, Mr. Bernstein?
Mr. Bernstein: Certainly not. Listen, Mr. Kane will change them to his kind of newspapermen in a week.
