> This is the essential point. Are changes for the better prevented by wicked men who know the changes to be advisable, but resist them out of self-interest? Or are they prevented by the difficulty of knowing for certain where wisdom lies? The class-war faction believe that it is well known what ought to be done; that we are divided between the poor and good who would like to do it, and the rich and wicked who, for reasons of self-interest, wish to prevent it; that the wicked have power; and that a revolution is required to depose them from their seats. I view the matter otherwise. I think it extremely difficult to know what ought to be done, and extremely difficult for those who know (or think they know) to persuade others that they are right; through theories, which are difficult and obscure when they are new and undigested, grow easier by the mere passage of time. --Keynes, 1934
