As to the "Temporary nature of knowledge capital" Some programmers want to learn a language or technology and continuously repeat the same basic project over and over again. I have been at it for more than a decade and am not using the same skill set that I started with - although some (*nix and SQL) have been in heavy use for quite awhile. I know programmers that started "back in the day" and tell horror stories of stacks of punch cards being knocked to the floor. They are now coding in a modern language or helping to port legacy applications. In programming - and many other professions, you need to stay current and adapt. Not to mention, you generally learn a lesson or two by simply dealing with people, working through large scale projects, and seeing technologies come and go. Some employers value this. Others opt for the cheapest salary available - and have results that prove that this is their approach.
