the evils arising from the unjust and unequal distribution of wealth are not incidents of progress,

but tendencies which must bring progress to a halt. They will not cure themselves, but, on the contrary, must, unless their cause is removed, grow greater and greater, until they sweep us back into barbarism by the road every previous civilization has trod. These evils are not imposed by natural laws; they spring solely from social maladjustments which ignore natural laws, and in removing their cause we shall be giving an enormous impetus to progress.
The poverty which in the midst of abundance pinches and embrutes men, and all the manifold evils which flow from it, spring from a denial of justice. In permitting the monopolization of the opportunities which nature freely offers to all, we have ignored the fundamental law of justice—for, so far as we can see, when we view things upon a large scale, justice seems to be the supreme law of the universe. But by sweeping away this injustice and asserting the rights of all men to natural opportunities, we shall conform ourselves to the law—we shall remove the great cause of unnatural inequality in the distribution of wealth and power; we shall abolish poverty; tame the ruthless passions of greed; dry up the springs of vice and misery; light in dark places the lamp of knowledge; give new vigor to invention and a fresh impulse to discovery; substitute political strength for political weakness; and make tyranny and anarchy impossible.
