I found these quotes while reading the SLTrib; their blog was quoting from a post on http://www.timesandseasons.org by Julie M. Smith. It is worthy of being read and reread.
According to then-member of the Quorum of the Twelve Apostles Spencer W. Kimball in an October 1953 General Conference address:
Now, all money is not lucre—all money is not filthy. There is clean money—clean money with which to buy food, clothes, shelter, and other necessities and with which to make contributions toward the building of the kingdom of God.
Clean money is that compensation received for a full day’s honest work. It is that reasonable pay for faithful service. It is that fair profit from the sale of goods, commodities, or service. It is that income received from transactions where all parties profit.
Compromise money is filthy, graft money is unclean, profits and commissions derived from the sale of worthless stocks are contaminated as is the money derived from other deceptions, excessive charges, oppression to the poor and compensation which is not fully earned. I feel strongly that men who accept wages or salary and do not give commensurate time, energy, devotion, and service are receiving money that is not clean. Certainly those who deal in the forbidden are recipients of filthy lucre. . . . I am sure that money is unclean when it is obtained through oppression, fraud[,] bribery, or through misrepresentations. . . . He that oppresseth the poor to increase his riches, and he that giveth to the rich, shall surely come to want (Prov. 22:16). Much is said about the hirer and the hired in the scriptures, and about the employer and the employee:
Go to now, ye rich men, weep and howl for your miseries that shall come upon you. Your riches are corrupted, and your garments are motheaten. Your gold and silver is cankered; and the rust of them shall be a witness against you, and shall eat your flesh as it were fire. Ye have heaped treasure together for the last days. Behold, the hire of the labourers who have reaped down your fields, which is of you kept back by fraud, crieth: and the cries of them which have reaped are entered into the ears of the Lord of sabaoth ( James 5:1-4). . . .
