One thing that bothered me about the article and your post, however, is the "google chef" comment is bugging you for the wrong reason.
You and the OP are in agreement with Pincus implicitly, if you believe that merit and contributions as an employee is what justifies the rewards of equity appreciation.
That's not how the world works. Warren Buffett did not lift a finger building railroads, soda pop, and newspapers. That's not why he is rich.
Pincus wants you to think of this portion of your compensation as an employee, instead of an investor. Charlie made money because he became an investor, not because he was a chef.
