Let them eat cake.
This was never said by Marie Antoinette. Jean-Jacques Rousseau, in his 1783 autobiography Confessions, relates that "a great princess" is said to have advised, with regard to starving peasants, "S’ils n’ont plus de pain, qu’ils mangent de la brioche," commonly translated as "If they have no bread, let them eat cake!" It has been speculated that he was actually referring to Maria Theresa of Spain.
