Interpretation in Mosiah

Mosiah

"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
Although it is not entirely clear, Zeniff seems to be criticized for having "many wives and concubines." 11:2
"And he [Zeniff] laid a tax of one fifth part of all they possessed."
Since Zeniff was a bad guy (who "did not keep the commandments of the Lord") and he taxed the people 20%, I guess God (or Joseph Smith) didn't approve of flat taxes -- or maybe taxes of any kind. 11:3
