Maybe true in Greek times but the Greeks didn't foresee the power and effectiveness of media control, sophisticated propaganda, and institutional dominance. Its a different ballgame today, what one might call the Golden Rule. He who has the gold makes the rules, is unaccountable, and see's no need to ever apologize.
He is also outnumbered by thousands to one. Pi$$ing off enough of those thousands could result in a bad outcome for the gold-holding rule-maker!
