Maybe, as this thread shows, we could start by doing some PR on ourselves around what the word ‘creative’ actually means.
For example, many people conflate ‘creativity’ with ‘wackiness’ or ‘funkiness’.
Whereas, in fact, it’s often the opposite, like doing a lot of research and business analysis to improve a back-end process which, in turn, enables a successful user experience at the front-end (to use an example from the area of design I work in).
When you say ‘Creative’ types, I think you actually mean ‘communicators’, like writers, graphic designers, interaction designers, etc. (It’s important to say what type of designer, because ‘designer’ on its own is more or less meaningless.) Communication is usually about problem solving, and there are established, proven, reliable and repeatable processes to solve problems. Selling that might be more successful than selling airy-fairy notions of ‘creativity’, with its overtones of unpredictability, unreliability and risk.
Something along those lines, maybe?
