If you work hard for your boss they laugh their way to the bank paying you the same flat salary and pocketing the profits of your labors.

To get there eventually (sadly?) you have to plan to get out from under others siphoning your productivity like that. Because the modern corporate culture has shifted to taking advantage of the best, rather than empowering them. Mostly because there is a surplus of (skilled) labor in most industries. If there wasn't, your boss would be treating you better because you are a scarce resource they don't want to lose because its either expensive or time consuming to replace.

And like the article says, "working hard" isn't invaluable.
