The great problem, of which these recurring seasons of industrial depression are but peculiar manifestations, is now, I think, fully solved, and the social phenomena which all over the civilized world appall the philanthropist and perplex the statesman, which hang with clouds the future of the most advanced races, and suggest doubts of the reality and ultimate goal of what we have fondly called progress, are now explained. _The reason why, in spite of the increase of productive power, wages constantly tend to a minimum which will give but a bare living, is that, with increase in productive power, rent tends to even greater increase, thus producing a constant tendency to the forcing down of wages._ In every direction, the direct tendency of advancing civilization is to increase the power of human labor to satisfy human desires—to extirpate poverty, and to banish want and the fear of want. All the things in which progress consists, all the conditions which progressive communities are striving for, have for their direct and natural result the improvement of the material (and consequently the intellectual and moral) condition of all within their influence. The growth of population, the increase and extension of exchanges, the discoveries of science, the march of invention, the spread of education, the improvement of government, and the amelioration of manners, considered as material forces, have all a direct tendency to increase the productive power of labor—not of some labor, but of all labor; not in some departments of industry, but in all departments of industry; for the law of the production of wealth in society is the law of “each for all, and all for each.”
