It makes sense: if you’re good at your job, you’ll be promoted. If you’re not good at your job, you won’t. People are rarely demoted, regardless of their job performance. This means that an employee will continue to be promoted until they reach a position for which they’re unfit. Because they do poorly in that position, they aren’t promoted to a higher one, and they’re stuck being incompetent at their job.
