This is what I see for my state: "The average salary for a Registered Nurse in Colorado with 25 years of experience ranges from $115,000 to over $140,000 annually".

A dev with the same experience I think is at least 50% more than this.

I suppose that I should have added "in my state" to my comment about comparable wages. I can't speak to any other regions.
