It is widely believed that our never-ending quest for material goods is part of the basic character of human beings.According to the popular belief, we may not like it, but there’s little we can do about it.

Despite its popularity, this view of human nature is wrong. While human beings may have a basic desire to strive towards something, there is nothing inevitable about material goods. There are numerous examples of societies in which things have played a highly restricted rule. In medievalEurope, the acquisition of goods was relatively unimportant. The common people, whose lives were surely poor by modern standards, showed strong preferences for leisure rather than money. In the nineteenth-and early twentieth-century United States, there is also considerable evidence that many working people also exhibited a restricted appetite for material goods.
Materialism is not a basic trait of human nature, but a specific product of capitalism. With the development of the market system, materialism "spilled over", for the first time, beyond the circles of the rich. The growth of the middle class created a large group of potential buyers and the possibility that mass culture could be oriented around material goods. This process can be seen not only in historical experiences but is now going on in some parts of the developing world, where the growth of a large middle class has contributed to extensive materialism and the breakdown of traditional values.
In the United States, the turning point was the 1920s—the point at which the "psychology of shortage" gave way to the "psychology of abundance". This was a crucial period for the development of modern materialism.Economy and discipline were out; waste and excess were in. Materialism flourished—both as a social ideology and in terms of high rates of real spending. In the midst of all this buying, we can detect the origins of modern consumer discontent.
This was the decade during which theAmerican dream, or what was then called "theAmerican standard of living", captured the nation’s imagination.But it was always something of an illusion.Americans complained about items they could not afford—despite the fact that in the 1920s most families had telephones, virtually all had purchased life insurance, two-thirds owned their own homes and took vacations, and over half had motor cars.
The discontent expressed by manyAmericans was promoted—and to a certain extent even created—by manufacturers. The explosion of consumer credit made the task easier, as automobiles, radios, electric refrigerators, washing machines—even jewelry and foreign travel—could be paid for in installments.By the end of the 1920s, 60 percent of cars, radios, and furniture were being purchased this way. The ability to buy without actually having money helped encourage a climate of instant satisfaction, expanding expectations, and ultimately, materialism.
According to the passage, materialism ______.
A、is a by-product of capitalism
B．originated from the circles of the rich
C．was first created among the middle class
