B.H. Roberts:

The agency of man would not be worth the name if it did not grant liberty to the wicked to fill the cup of their iniquity, as well as liberty to the virtuous to round out the measure of their righteousness.

Bruce R. McConkie:

No person shall “be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation.” There is included in this the right to property. It is pure unalloyed capitalism and is wholly repugnant to every principle of communism and of socialism, or fascism and of marxism. It is so sacred to Americans that twice they have amended their Constitution to preserve it unto themselves. The first occasion was in the 5th amendment just quoted, and the second in the 14th amendment which decrees, “No state shall … deprive any person of life, liberty, or property, without due process of law.” We cannot do away with the capitalistic system of free enterprise without first doing away with the supreme law of the land, the Constitution of the United States.

Mark E. Petersen:

How many of the Latter-day Saints truly believe in the Constitution of the United States? That Constitution stands for free initiative. That is free agency. In a business sense, we have spoken of it as free private enterprise. Are the Latter-day Saints as a people willing to accept the principle of free enterprise? There are some among us who are teaching that free enterprise is wrong. These same individuals would do away with the capitalistic system setting forth its many abuses. It is true that many abuses of the capitalistic system have taken place. Nevertheless, capitalism is an outgrowth of free enterprise in business. Free enterprise in business is an outgrowth of free enterprise in a general sense, and free enterprise in a general sense is free agency—the principle to which Latter-day Saints are committed. If we were to ask those who oppose free enterprise in business, including the capitalistic system, what they would put in the place of these things, they have but one answer, which is socialistic. They would have a government-operated and government-controlled business,** which is Socialism. Socialism is a step on the road to Communism.** Communism is anti-Christ. Are the Latter-day Saints willing to engage in a program that would lead to Communism? Are they willing to aid and abet the antichrist in any sense? Are they willing to accept Socialism instead of freedom? Not if they understand their religion.

* There are different degrees of state governance and control of the economy.
** Karl Marx said that socialism is the transitional period between capitalism and communism.
