The personality market, the most decisive effect and symptom of the great salesroom, underlies the all pervasive distrust and self-alienation so characteristic of metropolitan people. Without common values and mutual trust, the cash nexus that links one man to another in transient contact has been made subtle in a dozen ways, and made to bite deeper into all areas of life and relations. People are required by the salesman ethic and convention to pretend interest in others in order to manipulate them. In the course of time, and as this ethic spreads, it is got on to. Still, it is conformed to as part of one's job and one's style of life, but now with a winking eye, for one knows that manipulation is inherent in every human contact. Men are estranged from one another as each secretly tries to make an instrument of the other, and in time a full circle is made: one makes an instrument of himself and is estranged from it also.

"Modern man has transformed himself into a commodity; he experiences his life energy as an investment with which he should make the highest profit, considering his position and the situation on the personality market. He is alienated from himself, from his fellow men and from nature. His main aim is profitable exchange of his skills, knowledge, and of himself, his "personality package" with others who are equally intent on a fair and profitable exchange. Life has no goal except the one to move, no principle except the one of fair exchange, no satisfaction except the one to consume.p97."

The phrase ‘marriage market’ is used metaphorically and signifies that the mating of human populations is highly systematic and structured.

So it is with all the great leaders: the commodity they have to sell is personality. Mere ideas can be left to lesser men.

By "market" is meant the entire complex of institutions within which people buy and sell and hire and are hired and borrow and lend and trade and contract and shop around to find bargains.

An employer has no business with a man's personality. Employment is a specific contract calling for a specific performance... Any attempt to go beyond that is usurpation. It is immoral as well as an illegal intrusion of privacy. It is abuse of power. An employee owes no "loyalty," he owes no "love" and no "attitudes"--he owes performance and nothing else. .... The task is not to change personality, but to enable a person to achieve and to perform.

A group of people who think differently is a market.

A group of people who think alike is a mob.

A market is a group of buyers and sellers of a particular good or service. The buyers as a group determine the demand for the product, and the sellers as a group determine the supply of the product. Markets take many forms. Some markets are highly organized, such as the markets for many agricultural commodities. In these markets, buyers and sellers meet at a specific time and place, where an auctioneer helps set prices and arrange sales. More often, markets are less organized.

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.

The mechanism of the market was asserting itself and clamoring for its completion: human labor had to be made a commodity. Reactionary paternalism had in vain tried to resist this necessity. Out of the horrors of Speenhamland men rushed blindly for the shelter of a utopian market economy.

Since the values of the market were the highest criteria, persons also became valued as commodities which could be bought and sold. A person's worth is then his salable market value, whether it is skill or 'personality' that is up for sale. [...]
The market value, then, becomes the individual's valuation of himself, so that self-confidence and 'self-feeling' (ones experience of identity with one's self) are largely reflections of what others think of one, in this case the 'others' being those who represent the market. Thus contemporary economic processes have contributed not only to an alienation of man from man, but likewise to 'self-alienation' - an alienation of the individual from himself. As Fromm very well summarizes the point:

Since modern man experiences himself both as the seller and as the commodity to be sold on the market, his self-esteem depends on conditions beyond his control. If he is 'successful,' he is valuable; if he is not, he is worthless. The degree of insecurity which results from this orientation can hardly be overestimated. If one feels that one's own value is not constituted primarily by the human qualities one possesses, but by one's succes on a competitive market with ever-changing conditions, one's self-esteem is bound to be shaky and in constant need of confirmation by others. [Erich Fromm, Man for himself]

In such a situation one is driven to strive relentlessly for 'succes'; this is the chief way to validate ones self and to allay anxiety. And any failure in the competitive struggle is a threat to the quasi-esteem for one's self - which, quasi though it be, is all one has in such a situation. This obviously leads to powerful feelings of helplessness and inferiority.

The personality of a product is an amalgam of many things – its name, its packaging, its price, the style of its advertising, and, above all, the nature of the product itself.

Markets are social constructs that reflect the unique political-cultural construction of their business enterprises and nations.

The market is a system of mass cooperation.
