Ran across a long talk by Orson Pratt, given 3/9/1873.
He begins by quoting D&C 78:

ChristAndTheRichYoungRuler-300w3 For verily I say unto you, the time has come, and is now at hand; and behold, and lo, it must needs be that there be an organization of my people, in regulating and establishing the affairs of the storehouse for the poor of my people, both in this place and in the land of Zion—
4 For a permanent and everlasting establishment and order unto my church, to advance the cause, which ye have espoused, to the salvation of man, and to the glory of your Father who is in heaven;

5 That you may be equal in the bonds of heavenly things, yea, and earthly things also, for the obtaining of heavenly things.

6 For if ye are not equal in earthly things ye cannot be equal in obtaining heavenly things;

7 For if you will that I give unto you a place in the celestial world, you must prepare yourselves by doing the things which I have commanded you and required of you.

Then he quotes D&C 105:

3 But behold, they have not learned to be obedient to the things which I required at their hands, but are full of all manner of evil, and do not impart of their substance, as becometh saints, to the poor and afflicted among them;

4 And are not united according to the union required by the law of the celestial kingdom;

5 And Zion cannot be built up unless it is by the principles of the law of the celestial kingdom; otherwise I cannot receive her unto myself.

6 And my people must needs be chastened until they learn obedience, if it must needs be, by the things which they suffer. [I’m thinking he’s referring to the suffering resulting from the negative societal consequences of doing economics any way but His. ie. Pride Flu]

Then Pratt lowers the boom:

I have read these passages of new revelation for the benefit of the Latter-day Saints who are here this afternoon, and it is well enough for us to examine ourselves, to see whether we are living in strict accordance with them, and if we are not, to see whether there are any persons throughout all the Territory of Utah who are complying with them. In one of these revelations, given in March, 1831, before the Lord had led this people to Jackson County and before we knew where the New Jerusalem was to be built, or where the great central gathering place for the Latter-day Saints was to be, the Lord informed us, “That it is not given that one man should possess that which is above another, wherefore the world lieth in sin.” Now let me inquire of the Latter-day Saints, Are we all equal in the bonds of earthly things, or have we rich and poor in our midst? The answer that all would give to this question is, every person and every family has accumulated just as much wealth, as he or they could, for his or their own use only, and this order of things has existed amongst us since the Church was organized, nearly forty-three years. How much longer will this continue? How long will every family be for themselves, every man’s energy and ability be exerted only for himself and his family, every man grasping to enrich himself? He does not care about his neighbor, and if he thinks about him at all, the inquiry rises in his mind, “Have I got as much wealth as my neighbor, or as this or that person? If I have not I must strive to obtain as much; for if I have not as much as my neighbors I can hardly think to crowd myself into their society; for I have noticed that our wealthy citizens are creating distinctions of classes among us. If they get up a party in their own private dwellings, or a nice luxurious supper, for instance, it is generally only those who are wealthy in appearance who are invited, and unless I can accumulate as much wealth as they have, I shall be cast out and fall below into some other class.”
