I do think there is a correlation between how much a person makes and their willingness to collaborate and better themselves. Other professional, will spend time outside their normal routine to keep learning new ideas within their profession. The expectation is there for teachers, but only few take anything out of their professional development. A few teachers dread PD days. I feel that if we make the salary of a teacher more comparable to other professionals, then there might be more of a desire to keep learning their trade, bettering oneself. The expectation will be there to be the best that you can be. We may not be saving a life right then and there, like doctors, but we are directing many lives in the right direction.
