Surely you have heard about this guy, Jérôme Kerviel, who lost SEVEN BILLION DOLLARS of other people's money when he figured out how to make trades with French bank Société Générale's accounts without detection by his superiors? He had friends in the back office and had toiled in "the mine" — basically, glorified tech support — for years, and apparently he thought he had some sort of ingenious profit-making scheme to make billions. He'd show them! It almost worked — and then it all went horribly wrong! As traders go, he's now the biggest loser in history. Would you believe France is hailing him as a hero? I love France.
