Time-value is here understood to be that all-pervading difference in the values of uses and gratifications of wealth at different points of time. A comparison of the value of momently appearing uses of wealth is the rent problem. Here are, therefore, very different aspects of the value problem. The rent conception is earlier grasped by men, is nearer in point of logic; the concept of time-value has only recently been clearly recognized. If men lived only in the moment, they would be concerned only with rent; living in the future also, they are constantly regulating their acts with reference to time-value.
CHAPTER 18
RELATIVELY FIXED AND RELATIVELY INCREASABLE FORMS OF CAPITAL
§ I. HOW VARIOUS FORMS OF CAPITAL MAY BE INCREASED
The older and the modern way of viewing wealth
1. Men seek to increase income by increasing capital. Men may strive to increase their rents without expressing the rent-bearer in terms of capital. Peasant owners and small proprietors, toiling fondly on their little estates, seeking steadily a larger crop, a larger income, accomplish wonders in bringing waste land to a high state of cultivation. Working on the soil that is at once their livelihood and their home, they do not consciously reckon the value of the labor they are putting upon it. No money can buy that which to them is beyond price. But, in our money economy, efforts are largely directed toward the increase of the capital sum. Investment takes the form of putting in a sum of money in the hope of getting an income bearing a certain relation to it. The first thought is of the value of the wealth invested, which has been carefully measured and expressed in dollars and cents. Wealth looked at in the older way was valued for what it did immediately for its owner, for its concrete fruits; looked at in the modern way, it is valued as a marketable income-bearer readily convertible into a multitude of other forms. Thus investments come to be thought of in terms of general purchasing power, from which it is expected to realize an income of a given percentage.
