Through all the Employments of Life
Each Neighbour abuses his Brother;
Whore and Rogue they call Husband and Wife:
All Professions be-rogue one another:
The Priest calls the Lawyer a Cheat,
The Lawyer be-knaves the Divine:
And the Statesman, because he's so great,
Thinks his Trade as honest as mine.

Peachum, Act I, air 1. - The Beggar's Opera (1728)
