I happened to think of another reason for RoR and Python developers to maybe be earning more. They're the hot languages for startups right now. Ton of capital chasing startups these days. Probably partly a quirk of the dogmatic need to use of these languages in those companies (?), creating artificial supply constraint in that industry.
Also, I see a lot less offshoring happening among firms that use these languages. So yeah, I guess they've been associated with "doing things right" which implicitly means no cheap offshoring, and is also associated with higher end engineers.
One interesting quirk about RoR listings I've seen - they ALL seek senior level people with 5-10 yrs of experience. Quite ambitious when you consider how long RoR has been around. Haha.
So perhaps that is the rub. When someone seeks a RoR team... its really just code for wanting to work with senior on-site talent. No juniors and no outsourcing. And thus this drives rates higher, not just due to supply/demand but also because of percieved quality/branding that goes along with it.
