You project an image on a wall interesting enough for people to stop and look at it. You show them another, then another. If you gain their interest enough they will pay you to keep showing them new images.'
Thus is born an industry.
The camera loves some people; an accident of genetic inheritance.
Thus is born the 'Star'.
By the dynamics of the medium; a performance done and redone untill it is perfect; that perfection caught on a easily replicatable media and shown countless time to countless people; a lucky few become far wealtier than their actual value as a human being; and you have the angst and endless self reflection of those trying to reconcile the disparity between reward and worth.
The whole thing is an illusion that provides a momentary diversion from cares of the day.
A diversion.
An amusement.
Nothing more.
