But by far the greater part of these evils are wholly unnecessary. If the civilized portion of mankind could be induced to desire their own happiness more than another's pain, if they could be induced to work constructively for improvements which they would share with all the world rather than destructively to prevent other classes or nations from stealing a march on them, the whole system by which the world's work is done might be reformed root and branch within a generation. From the point of view of liberty, what system would be the best? In what direction should we wish the forces of progress to move? From this point of view, neglecting for the moment all other considerations, I have no doubt that the best system would be one not far removed from that advocated by Kropotkin, but rendered more practicable by the adoption of the main principles of Guild Socialism. Since every point can be disputed, I will set down without argument the kind of organization of work that would seem best. Education should be compulsory up to the age of 16, or perhaps longer; after that, it should be continued or not at the option of the pupil, but remain free (for those who desire it) up to at least the age of 21. When education is finished no one should be COMPELLED to work, and those who choose not to work should receive a bare livelihood, and be left completely free; but probably it would be desirable that there should be a strong public opinion in favor of work, so that only comparatively few should choose idleness. One great advantage of making idleness economically possible is that it would afford a powerful motive for making work not disagreeable; and no community where most work is disagreeable can be said to have found a solution of economic problems. I think it is reasonable to assume that few would choose idleness, in view of the fact that even now at least nine out of ten of those who have (say) 100 pounds a year from investments prefer to increase their income by paid work.
