Because we as programmers need to know how to progam: learning trumps all. Thus:

    learning > biz > user > ops > maintainer > author

There was that bit

    dev > *

meaning resume-driven development, but in reality it is

    learning > *

And that's the conflict programmers experience in corporate structures, for example the hassle programmers experience when they interview for a position. Employers know it too but they try to shirk it.
