> THE GREAT PROBLEM IS SOLVED. We are able to explain social phenomena that have appalled philanthropists and perplexed statesmen all over the civilized world. We have found the reason why wages constantly tend to a minimum, giving but a bare living, despite increase in productive power:
> As productive power increases, rent tends to increase even more — constantly forcing down wages.
> Advancing civilization tends to increase the power of human labor to satisfy human desires. We should be able to eliminate poverty. But workers cannot reap these benefits because they are intercepted. Land is necessary to labor. When it has been reduced to private ownership, the increased productivity of labor only increases rent. Thus, all the advantages of progress go to those who own land. Wages do not increase — wages cannot increase. The more labor produces, the more it must pay for the opportunity to make anything at all.
