Are You a Blue Collar or White Collar Developer?

jammag writes: Some developers have gone to four-year universities where they've also studied subjects like history and sociology, while other coders go to vocational schools and focus purely on writing great software. So why, asks a longtime developer, is there a stigma attached to not having a four-year degree, when 'blue collar' coders might be better trained? Why does the software industry keep emphasizing this difference — and generally giving better pay to four-year grads? Isn't being a developer about real skill level, not the piece of paper on the wall?
