"For the earth is full, and there is enough and to spare; yea, I prepared all things, and have given unto the children of men to be agents unto themselves.
Therefore, if any man shall take of the abundance which I have made, and impart not his portion, according to the law of my gospel, unto the poor and the needy, he shall, with the wicked, lift up his eyes in hell, being in torment." (D&C 104: 17-18)
The implicit argument here is that there are enough resources for the appropriate use of all men, and that it's our collective failure to allocate them adequately that leads to poverty and starvation. Amartya Sen was awarded a Nobel Prize for saying just that.
