> Anyway, consider the following scenario. Bob makes $10 an hour, and produces $100 of value. Obviously, this is a great bargain for Bob's employer. So much so, that another employer should be perfectly willing to offer Bob $11 to lure him away. Another sweetens it to $12 and Bob moves again. Rinse, repeat until Bob is making $100 minus the opportunity cost.

Except if the companies in question are Google, Apple...
