Many of the supposed "heroes" of the past were liars, frauds, and butchers to varying degrees. The association of fame with entertainers, for all its flaws, departs from earlier concepts of heroic brutality and martial virtue. Most of today’s famous people have had to persuade consumers to offer their allegiance and their dollars. Nowadays fame is attained through a high-stakes game of pursuit and seduction, rather than a heroic contest or a show of force in battle.
