It wasn't mentioned, I was saying profit should be based on the demands of your job. Celebrities, not only are just lucky to have been born with talent, but are also usually born in the right place at the right time or are just lucky. There are so many other people out there that are just as good, but they aren't ever going to be discovered.
Its just that their work isn't that horrible and the fact people volunteer to do tha same kind of work because they enjoy it, and not for loads of money (for local theater, or in high school, during play productions) but for the simple fact the enjoy doing so still undergo the same pressures. The reason they still do it is because its a un thing to do. You can hardly say that for a miner, or a trucker, to whom spends months away from home, alone with any wife and children he might have.
Whats that horrible about acting under hot lights, and making jokes on the set, and laughing when someone messes up, but knowing thats not a problem because the scene can be reshot? Or singing in front of a crowd that paid good money just to see you shine? I'm sure there are pressures to the job, but no real labor. And isn't that what work is about? Committing yourself to something and laboring to earn a living?
