No doubt. I've even encountered somebody who stomped his feet and said they weren't going to write test code for QA because that was beneath them.

I think that's because the entire industry devalues both QA/testing and maintenance. Even in places that aren't the Valley these two roles are given a lower social status than other developer roles. The budgets and recognition for teams in both domains is typically much smaller than others, and QA especially is usually among the first on the chopping block during a retrenchment.

We as a whole have made these roles seem less valuable and less values, so to me it's not surprising that folks don't want to do them.
