According to Hugh Nibley, king Benjamin's speech has three parts. Notice in the first part they are celebrating. He is telling them that the good times they have been having are just a prelude to great things to follow and to eternal life when they can have joy and salvation forever if they do the right thing. the second part is saying don't let it go to your head. Notice how he cuts them down in that second part--you are nothing, you are the dust, you poor miserable creatures, etc. What a way to be talking to the people at a great national celebration. Then the third part is devoted entirely to economics--what it means for it to go to your heads. Then you will get this idea of inequality resulting in greed. King Benjamin says it will destroy you here and it will damn you forever. [Hugh W. Nibley, Teachings of the Book of Mormon, Semester 1, p. 465]
