"In so far as this management creates an assured strategic advantage for any given business concern, the result is a vested interest. This may then eventually be capitalized in due form, as a body of intangible assets. As such it goes to augment the business community's accumulated wealth. And the country is statistically richer per capita. A vested interest is a marketable right to get something for nothing. This does not mean that the vested interests cost nothing. They may even come high. Particularly may their cost seem high if the cost to the community is taken into account, as well as the expenditure incurred by their owners for their production and up-keep. Vested interests are immaterial wealth, intangible assets. As regards their nature and origin, they are the outgrowth of three main lines of businesslike management: (a) Limitation of supply, with a view to profitable sales; (b) Obstruction of traffic, with a view to profitable sales; and (c) Meretricious publicity, with a view to profitable sales."
