[8] Profit is here used colloquially to denote the excess of the value of an article over its cost.

[9] When one of the conditions of earning a wage is the keeping up of a certain state, subsistence wages may reach a figure to which the term seems ludicrously inappropriate. For example, a fashionable physician in London cannot save out of £1,000 a year; and the post of Lord Lieutenant of Ireland can only be filled by a man who brings considerable private means to the aid of his official salary of £20,000.

[10] The current rate must, under present conditions, eventually fall to zero, and even become “negative.” By that time shares which now bring in a dividend of 100 per cent, may very possibly bring in 200 or more. Yet the fall of the rate has been mistaken for a tendency of interest to disappear. It really indicates a tendency of interest to increase.

[11] This excess of the product of labor over its price is treated as a single category with impressive effect by Karl Marx, who called it “surplus value” (mehrwerth).
