My favourite historical instance of public pisstaking of the rich and famous comes from ancient Athens.
Pericles, came to power about 461BC, was kind of like the Barack Obama of his day, universally admired (almost). Unbelievably powerful, led Athens in the war against the Persians, got the Acropolis built, famous orator yada yada.
He had his detractors though. There were mutterings about his private life and his treatment of working class Athenians. Aristophanes put on a comedy at Athens' regular theatrical festival (think of it as the SNL of ancient Greece). All the Athenians high and low were there on opening night, Pericles himself was obvs in the front row.
the play opens with a scene in the Kerameikos cemetary in which "Pericles" is shown with his meat n 2 veg out, doing something very graphic with a young man up against a gravestone.
Everyone in the theatre falls about laughing, probably even Pericles had to crack a smile
My point being - humans having been taking the mickey out of their social betters since we first swung down from the trees. This supposed 'age of deference' never, ever, ever existed.
