Of course, there are two other factors to consider.
First is talent and ability. Not all of us have the same talents. I can't run the four-minute mile, nor am I a particle physicist. And it most cases, we can't change our talent and abilities, although we can hone what we already have. And yes, this is "unfair" in that you are born with a certain set of smarts or body type, and really can't do too much with that.
But on the other hand, some seriously ugly people become movie stars, and some fairly dumb people become Billionaires. They have to work at it more, though.
The other aspect is that we can't all be in charge. In any organization, there are leaders and followers, and the largest problem facing American industry today is that there are too many Vice-Presidents and not enough people actually working.
So most of us are destined to be drones. But what level of droneship is going to depend not just on your talents and abilities, but also the choices you make.
