Which statement is most accurate?

A) Communism is completely dead as an economic system.
B) Communism is the wave of the future.
C) Although the United States is nominally a capitalist society,we have a basically communist economy system.
D) The American economy is guided almost entirely by the price mechanism.

The statement that "The American economy is guided almost entirely by the price mechanism" is the most accurate. While some argue that elements of communism exist in the U.S. economy, such as government intervention and regulation, the dominant economic system is still based on market principles and the determination of prices by supply and demand. Communism as an economic system has largely failed, and while there may be some pockets of support for it ideologically, it is not a viable alternative to capitalism in practice.
