The "corporate ladder" analogy is broken, because the ladder is tree shaped. It's statistically impossible to climb tree shaped ladders, because they get exponentially smaller at the top, and there are too many levels. "Climb the corporate n-ary tree" would be a better analogy, for large values of n, and large tree height. It should be obvious to computer scientists, via pigeonhole arguments, why this isn't statistically feasible.

In any case, it's probably easier to find loopholes, like startups, or being an early arrival to an industry, or starting at a smaller company that inflates later, or tunneling your way between points in the corporate topology, by switching from one company to another, if you're ambitious. But betting against statistics never pays.
