Some reasons that I don't think have been covered yet:

- experienced programmers are promoted out of the tech track - it causes all sort of problems, people keep reinventing the wheel, they are forced to relearn through their own mistakes, transfer of knowledge and skills is hampered

- (probably as a consequence of the first point) people with 3 years of experience are believed to be senior programmers

- worse even - experienced programmers are promoted to non-coding roles aka architects. Over time they increasingly disconnect from the tangible artifact (code) while still hanging onto a false belief that they can function just fine by embracing it through a metaphor (diagrams, etc.) ("Simulacra and simulation"?.. but possibly I'm digressing)
