"And even I, myself [me, myself, and I, i.e., Mosiah], have labored with mine own hands that I might serve you, and that ye should not
be laden with taxes."
(Mosiah was a card-carrying member of the Republican party.) 2:14
"Administer of your substance unto him that standeth in need; and ye will not suffer that the beggar putteth
up his petition to you in vain, and turn him out to perish." 4:16
"Ye ought to impart of the substance that ye have one to another." 4:21
"Impart of your substance to the poor, every man according to that which he hath, such as feeding the hungry,
clothing the naked, visiting the sick and administering to their relief." 4:26
"And he [Noah] laid a tax of one fifth part of all they possessed."

Alma seemed to favor progressive taxation and a welfare system. He demanded little of those with little, and more from
those with more to give, "and to him that had not should be given." 18:27
