In S1E18, Paris can’t stop smiling after her date with Tristan. Rory responds “Good, then it’s the perfect time to talk about our overtaxed peasants,” referring to their model government project. Paris says happily, “Oh, let them eat cake.”
“Let them eat cake,” is a famous phrase attributed to Marie Antoinette, Queen of France. The phrase was supposedly her response to learning that the lower classes had no bread to eat, and demonstrates her complete lack of understanding of the common people. According to some sources, though, the quote was misattributed (similar sayings were attributed to several other upper-class Frenchwomen). Some say Marie Antoinette was actually pretty nice and charitable, but nevertheless, tales of her extravagance contributed to the tension that sparked the French Revolution.
