The ownership of the material equipment gives the owner not only the right of use over the community's immaterial equipment, but also the right of abuse and of neglect or inhibition. This power of inhibition may be made to afford an income, as well as the power to serve; and whatever will yield an income may be capitalised and become an item of wealth to its possessor. Under modern conditions of investment it happens not infrequently that it becomes pecuniarily expedient for the owner of the material equipment to curtail or retard the processes of industry,--"restraint of trade." The motive in all such cases of retardation is the pecuniary expediency of the measure for the owner (controller) of capital,--expediency in terms of income from investment, not expediency in terms of serviceability to the community at large or to any fraction of the community except the owner (manager). Except for the exigencies of investment, _i.e._, exigencies of pecuniary gain to the investor, phenomena of this character would have no place in the industrial system. They invariably come of the endeavors of business men to secure a pecuniary gain or to avoid a pecuniary loss. More frequently, perhaps, manoeuvers of inhibition--advised idleness of plant--in industry aim to effect a saving or avoid a waste than to procure an increase of gain; but the saving to be effected and the waste to be avoided are always pecuniary saving to the owner and pecuniary waste in the matter of ownership, not a saving of goods to the community or a prevention of wasteful consumption or wasteful expenditure of effort and resources on the part of the community. Pecuniary--that is to say, differential--advantage to the capitalist-manager has, under the regime of investment, taken precedence of economic advantage to the community; or rather, the differential advantage of ownership is alone regarded in the conduct of industry under this system.
