People do the designing and architecture and programming just because it all pays well, not because they have a love for the craft.

True.
I like programming and tend to pride myself in making good code, but when I see other's attitude at work, it makes me reevaluate what I care about.

Perhaps this is the reason of the memetic difference between corporate code quality vs OSS code quality. When I contribute to Open Source (at least to other's projects), I see myself try to be as considerate as possible of multiple factors that I wouldn't even care of at work.
