Read this passage from a fictional letter by a Haitian aristocrat: The Haitian Revolution has been a complete disaster. All of my friends are poorer now than when the revolution started. We were the most productive, hardest working people on the island, but now our fortunes have been seized by corrupt politicians. Even the slaves who worked on my plantation were much happier before the revolution; I'm positive they'd like things to go back to the way they were.
