A few year ago the WSJ discussed how Cirque du Soleil recruits special performers but not so unique that they cannot be replaced or duplicated.

The greater a company (and the "investment") gets, the stable profit (like: patent stock, improvements planned for years ahead by selling number forecast to please investors) becomes the main goal, and the control over the replaceable employees is the way.
