🤦 Please read Chapter 18 of Human Action. https://mises.org/online-book/human-action/chapter-xviii-action-passing-time/2-time-preference-essential-requisite-action A teaser: "The theorem of time preference must be demonstrated in a double way. first for the case of plain saving in which people must choose between the immediate consumption of a quantity of goods and the later consumption of the same quantity. Second for the case of capitalist saving in which the choice is to be made between the immediate consumption of a quantity of goods and the later consumption either of a greater quantity or of goods which are fit to provide a satisfaction which--except for the difference in time--is valued more highly." --> Both plain savings (i.e., hoarding) and investment are expressions of time preference. On the productivity of plain savings: "If an individual employs a sum of money not for consumption but for the purchase of factors of production, saving is directly turned into capital accumulation. If the individual saver employs his additional savings for increasing his cash holding because this is in his eyes the most advantageous mode of using them, he brings about a tendency toward a fall in commodity prices and a rise in the monetary unit’s purchasing power....The effect of our [p. 522] saver’s saving, i.e., the surplus of goods produced over goods consumed, does not disappear on account of his hoarding. The prices of capital goods do not rise to the height they would have attained in the absence of such hoarding. But the fact that more capital goods are available is not affected by the striving of a number of people to increase their cash holdings. If nobody employs the goods--the nonconsumption of which brought about the additional saving--for an expansion of his consumptive spending, they remain as an increment in the amount of capital goods available, whatever their prices may be. Those two processes--increased cash holding of some people and increased capital accumulation--take place side by side."
