As has already been observed, the expression of ideas, such as through publication or broadcasting, is a productive process requiring the allocation of land, labor, and capital resources (cf. pp. 4.11:145-7, 5.2:47-51). As state control over these resources increases in a mixed economy, the authorities acquire an effective capacity to quash expression of opposing ideas. Indeed, in a statist environment, parties and individuals remain in power only insofar as they are willing to exercise this capacity more ruthlessly than their rivals. If these and similar measures discussed in the last few pages should fail, the authorities can impose outright censorship on the media. Such tactics, though extreme, are more readily accepted in the wake of other precedent-setting violations of the constitution, particularly in the prevailing atmosphere of national crisis. Regardless of whether the suppression of opposing ideas is accomplished by direct censorship or by withholding resources, one of the major obstacles to the juggernaut of state power is successfully eliminated.
