This is more about scarsity of certain jobs. We require a lot of 'on the ground' workers, e.g. software developers, and orders of magnitude fewer CEOs, CIOs, directors, etc. It's similar to someone wanting to get into a management position. Once the position is filled, and the person is doing at the very least "slightly above awful" job, you won't hire a manager for that team for quite some time.
