in preparing or marketing produce. If such “good will” is attached to a person rather than to the place, it is not wealth, but power. The last two are seldom distinctly enumerated by the assessor, yet they are clearly estimated in any exchange of places or transfer of titles. They are owned, used and transferred like other forms of wealth, and save future exertions to obtain them. All these are wealth because they contribute to welfare through being accumulated materials to meet future wants, and are to be measured in any estimate by their relation to the wants they will satisfy and the exertions they will save. _Future wants certain._—Wants and exertions are readily seen to be at the foundation of all ideas of wealth as indicated above. If we are uncertain as to the continuance of any wants or uncertain as to the conditions for meeting those wants, we stop accumulation of materials for satisfying them. Exertion stops unless the satisfaction to be gained by our effort is foreseen with a reasonable certainty. The farmer is never absolutely sure of returns for his labor upon the cornfield; but he is reasonably certain, and is absolutely certain that the crop will not come without labor. This assumed continuance of individual wants and their relations gives the grand motive for wealth gathering. The means of protection and support for physical life will be needed by ourselves and our children. Tools of better form and machinery of better manufacture will be needed to reduce exertion in future. Reduced exertion for a given satisfaction will mean a fuller supply of things we are going to need still. If these wants are fully met, we are going to have leisure to satisfy larger and higher wants. It is the certainty that each advance of wealth will bring advancing wants to consume more wealth, that gives a genuine motive to activity in gaining wealth, i.e., in accumulating the things to be used. The degree of uncertainty in all future plans leads to over-estimating the importance of gold, diamonds or any forms of wealth that can most easily be transferred between places or individuals, or be turned to account in each change of necessities. _Ownership._—The importance of wants and exertion emphasizes the importance of the individual self in all ideas of wealth. The _ownership_ of one’s _own_ abilities and their products is absolutely essential to his care for accumulation, and that care is in proportion to his security in such ownership. Directly or indirectly, every exertion and every sacrifice must depend upon confidence that it will bring its object; but wealth-getting has no object without control, in some measure, of results. This fact makes individual ownership an essential to the highest exertion, a natural sequence to the right of liberty.
