FWIW, some version of your rant occurs in almost every industry. Even doctors have hospital administrators complaining about how arrogant and non-business minded they are, how they are opportunistically defending their turf and so on. What you're talking about is not specific to devs but a general symptom of politics and friction between the different layers of an organization. Devs always lean more cynical than the rest of the org, but the "prima donna devs refusing to acknowledge the need to deliver" schema only emerges in poorly managed organizations and teams. There is always some push and pull, but usually it's within a healthy balance.
