I've read a long time ago an article about why managers should appreciate the devs., and there was analogy drawn to the 7 samurais movie: that a company can't really offer much to an engineer, and that the engineer chooses to help the company -- like the samurais helped the villagers.
I thought that was on joelonsoftware.com, or codinghorror.com; but the search did not bring any result. Does it ring a bell to anyone? Anyone?
