In Mosiah 7-19 we are told that Ammon and other Nephites from Zarahemla stumbled upon their brethren in Lehi-Nephi. We are told that the Lehi-Nephite decline started when King Noah raised income taxes from 10% to 20%, and culminated in their subjection to the Lamanites, who taxed them at a rate of 50%. Modern readers may wonder at this; why would the Nephites feel enslaved when many “free” nations nowadays have had much higher tax rates? (The USA had rates as high as 91%, and when Ronald Reagan won the US presidency in 1980, the top tax rate was 70%.) The “supply side” school of economic thought may provide an answer.
