“The opinions that the price of commodities depends solely on the proportion of supply and demand, or demand to supply, has become almost an axiom in political economy, and has been the source of much error in that science.”

“Labor is like any other commodity in the market — increase the demand for it and you increase the price of it. Reduce the supply of black labor by colonizing the black laborer out of the country, and by precisely so much you increase the demand for and wages of white labor.”

“Demand and supply are the opposite extremes of the beam, whence depend the scales of dearness and cheapness; the price is the point of equilibrium, where the momentum of the one ceases, and that of the other begins.”

“The worker's existence is thus brought under the same condition as the existence of every other commodity. The worker has become a commodity, and it is a bit of luck for him if he can find a buyer, And the demand on which the life of the worker depends, depends on the whim of the rich and the capitalists.”

“Profits and prices are the street signs of the economy. Only fools flout them. The much–maligned price system works not only to secure supply but to conserve.”

“One of the most important axioms is, that as the quantity of any commodity, for instance, plain food, which a man has to consume, increases, so the utility or benefit derived from the last portion used decreases in degree. The decrease in enjoyment between the beginning and the end of a meal may be taken as an example. And I assume that on an average, the ratio of utility is some continuous mathematical function of the quantity of commodity. This law of utility has, in fact, always been assumed by political economists under the more complex form and name of the Law of Supply and Demand. But once fairly stated in its simple form, it opens up the whole of the subject.”

William Stanley Jevons (1835–1882) English economist and logician
