“Freedom and freedom from hunger need not be mutually exclusive. Revenge and cruelty threaten the former; greed threatens the latter. If the Government of the free, by the free and for the free wants to sustain the free State, it has to go hammer and tongs against the enemies of freedom, whether these are revengeful, cruel and violent mobs or their ideological supporters or the greedy who bleed the free so that the hungry will join the mobs.”
