The princes and slaves line is actually a reference to the Bible. Ecclesiastes 10:7, to be exact: "I have seen servants upon horses, and princes walking as servants upon the earth."
I think the whole song is at least thematically related to the book of Ecclesiastes.
"All things are full of labour; man cannot utter it: the eye is not satisfied with seeing, nor the ear filled with hearing."
