61) The American economic system is organized around a basically private-enterprise, market-oriented economy in which consumers largely determine what shall be produced by spending their money in the marketplace for those goods and services that they want most. Private businessmen, striving to make profits, produce these goods and services in competition other businessmen; and the profit motive, operating under competitive pressures; largely determines how these goods and services are produced. 62) Thus, in the American economic system it is the demand of individual consumers, coupled with the desire of businessmen to maximize profits and the desire of individuals to maximize their incomes that together determine what shall be produced and how resources are used to produce it.
An important factor in a market-oriented economy is the mechanism by which consumer demands can be expressed and responded to by producers. 63) In the American economy, this mechanism is provided by a price system, a process in which prices rise and fall in response to relative demands of consumers and supplies offered by seller-producers. If the product is in short supply relative to demand, the price will be bid up and some consumers will be eliminated from the market. ) If, on the other hand, producing more of a commodity results in reducing its cost, this will tend to increase the supply offered by seller-producers, which in turn will lower the price and permit more consumers to buy the product. Thus, price is the regulating mechanism in the American economic system.
65) The important factor in a private-enterprise economy is that individuals are allowed to own productive resources (private property), and they are permitted to hire labor, gain control over natural resources, and produce goods and services for sale at a profit. In the American economy, the concept of private property embraces not only the ownership of productive resources but also certain right to determine the price of a product or to make a free contract with another private individual.

If, on the other hand, producing more of a commodity results in reducing its cost, this will tend to increase the supply offered by seller-producers, which in turn will lower the price and permit more consumers to buy the product.

【单选题】Why isn’t the word "sir" commonly used in Britain() A.Because it sounds too servile and is likely to cause embarrassment. B.Because it can only be used in some certain occupations. C.Because it is an ...

A.
As regards social conventions, we must say a word about the well known English class system. This is an embarrassing subject for English people, and one they tend to be ashamed of, though during the present century class-consciousness has grown less and less, and the class system less rigid. But it still exists below the surface. Broadly speaking, it means there are two classes, the "middle class" and the "working class". (We shall ignore for a moment the old "upper class", including the hereditary aristocracy, since it is extremely small in numbers; but some of its members have the right to sit in the House of Lords, and some newspapers take a surprising interest in their private life.) The middle class consists chiefly of well to do businessmen and professional people of all kinds. The working class consists chiefly of manual and unskilled workers.
B.
The most obvious difference between them is in their accent. Middle class people use slightly varying kinds of "received pronunciation" which is the kind of English spoken by BBC announcers and taught to overseas pupils. Typical working class people speak in many different local accents which are generally felt to be rather ugly and uneducated. One of the biggest barriers of social equality in England is the two class education system. To have been to a so called "public school" immediately marks you out as one of the middle class. The middle classes tend to live a more formal life than working class people, and are usually more cultured. Their midday meal is "lunch" and they have a rather formal evening meal called "dinner", whereas the working man’s dinner, if his working hours permit, is at mid-day, and his smaller, late evening meal is called supper.
C.
As we have said, however, the class system is much less rigid than it was, and for a long time it has been government policy to reduce class distinctions. Working class students very commonly receive a university education and enter the professions, and working class incomes have grown so much recently that the distinctions between the two classes are becoming less and less clear. However, regardless of one’s social status, certain standards of politeness are expected of everybody, and a well bred person is polite to everyone he meets, and treats a laborer with the same respect he gives an important businessman. Servility inspires both embarrassment and dislike. Even the word "sir", except in school and in certain occupations (e.g. commerce, the army, etc.) sounds too servile to be commonly used.
