Capital is concentrated social force, while the workman has only to dispose of his working force. The contract between capital and labour can therefore never be struck on equitable terms, equitable even in the sense of a society which places the ownership of the material means of life and labour on one side and the vital productive energies on the opposite side. The only social power of the workmen is their number. The force of numbers, however is broken by disunion. The disunion of the workmen is created and perpetuated by their unavoidable competition among themselves.
