[5] Should the connection at this point with the main argument of the paper as set forth in the earlier section seem doubtful or obscure, it may be called to mind that these dubious enterprises in dissipation are cases of investment for a profit, and that the "capital goods" engaged are invested wealth yielding an income, but that they yield an income only on the fulfillment of two conditions: (_a_) the possession and employment of these capital goods enables their holder to turn to account the common stock of technological proficiency, in those bearings in which it may be of use in his enterprise; and (_b_) the limited amount of wealth available for the purpose enables their holder to "engross" the usufruct of such a fraction of the common stock of technological proficiency, in the degree determined by this limitation of the amount available. In so far, these enterprises are like any other industrial enterprise; but beyond this they have the peculiarity that they do not, or need not, even ostensibly, turn the current knowledge and use of ways and means to "productive" account for the community at large, but simply take their stand on the (institutionally sacred) "accomplished fact" of invested wealth. They have less of the fog of apology about them than the common run of business enterprise. [6] This statement may not seem clear without indicating in a more concrete manner some terms in which to measure the relative differential advantage and disadvantage which so emerge in such a case of prerogative or privilege. Where, as in the earlier, non-pecuniary phases of culture, no price test is applicable, the statement in the text may be taken to mean that the differential disadvantage at the cost of which the differential benefit in question is gained is greater than the beneficiary would be willing to undergo in order to procure this benefit. [7] A doubt has been offered as to the applicability of this characterization to such intangible assets as a patent right and other items of the same class. The doubt seems to arise from a misapprehension of the analysis and of its intention. It should be remarked that there is no intention to condemn or disapprove any of the items here spoken of as intangible assets. The patent right may be justifiable or it may not: there is no call to discuss that question here. Other intangible assets are in the same case in this respect.
