Life is not fair, and you can't fix it. Play the cards you're dealt. The good news is every hand can be a winner in life (as in poker), it's all how you play. You get to choose.
Me, I will never be tall or handsome or muscular or have depth perception or have hand-eye coordination. I'm only good at one thing, and I take advantage.

I don't think the fatalistic attitude towards changing the system is any more (or, as much as I hate to admit it, less) reasonable than the "you could be Steve jobs too." Odds for both are pretty bleak, albeit non zero.
As advice to an individual in a rotten system, "make the most of what you've got" is fair enough. But when folks talk about politics they're not usually fishing for personal career advice. So when you bring this up in that context, either you've missed the point, or you're trying to distract folks from the issue at hand.
You don't have to build a trillion dollar company to be nicely successful, but using a nicely successful person as an anecdote is impractical because they are not public figures. But they are still all over the place, in plain sight. It's well within an ordinary person's ability to become one.
