From his “Road to Serfdom”:
Everything which might cause doubt about the wisdom of the government or create discontent will be kept from the people. The basis of unfavorable comparisons with elsewhere, the knowledge of possible alternatives to the course actually taken, information which might suggest failure on the part of the government to live up to its promises or to take advantage of opportunities to improve conditions–all will be suppressed. There is consequently no field where the systematic control of information will not be practiced and uniformity of views not enforced.
– F. A. Hayek
