In an address to LDS youth in June 1940, J. Reuben Clark spoke of a civilization called Jaredites who had lived on the American continent about 2000 years before Christ. President Clark said:
"We are not given the step-by-step backsliding of this Jareditic civilization till it reached the social and governmental chaos the record sets out, but those steps seem wholly clear from the results. Put into modern terms, we can understand them. First, there was a forsaking of the righteous life, and the working of wickedness; then must have come the extortion and oppression of the poor by the rich; then retaliation and reprisal by the poor against the rich; then would come a cry to share the wealth which should belong to all; then the easy belief that society owed every man a living whether he worked or not; then the keeping of a great body of idlers...
"When community revenues failed to do this, as they always have failed and always will fail, a self-helping by one to the goods of his neighbor; and finally when the neighbor resisted, as resist he must, or starve with his family, then death to the neighbor and all that belonged to him. This was the decreed 'fulness of iniquity.'
"Then came the end; the Jaredites were wiped out in accordance with 'the everlasting decree of God.'"
"And now, we can behold the decrees of God, concerning this land, that it is a land of promise; and whatsoever nation shall possess it shall serve God, or they shall be swept off when the fulness of his wrath shall come upon them. And the fulness of his wrath cometh upon them when they are ripened in iniquity." (Book of Mormon, Ether 2:9)
