The Following Is an Excerpt from West German Chancellor Ludwig

The following is an excerpt from West German chancellor Ludwig Erhard's reflections on the expansion of consumption in postwar Europe (Evaluating the Evidence 28.1) : "Consumer credit enables goods to be produced which could otherwise not find a market. . . . Now, consumer credit goes a step further and initiates an expansion of production (e.g. of refrigerators) , and this expanded production creates new income which in its turn appears as additional purchasing power on the market. The volume of goods at the disposal of the economy has in other words been built up to a higher level, the national product and the national income have been extended. . . . In this connection of course the question of magnitude is of vital importance. Consumer credit cannot carry, but can usefully supplement an upswing of the economy as a whole. . . . The use of consumer credit [is] one of the means capable of subserving a general policy aimed at expanded consumption. . . ."
According to Erhard, why is consumer credit a good thing?

A) It enables common people to buy the same products as the wealthy.
B) It allows for an expansion of production, which creates new income and purchasing power.
C) It eliminates the need to wait until enough has been saved to make the desired purchase.
D) It can carry an upswing of the economy on its own.
