Justice is a laudable goal.  A constant theme of the psalmist and the end and purpose of God's law.  The author, Elder Thompson, seems to equate inequality with injustice.  Does he think it is unjust that men are unequal?  Many do.  

I will strive to be just in all my dealings.  That is my fight.  It is my duty to God.  It is obedience to His will.
