One can make an educated guess at the correct salary level by identifying another large profession whose ordinary members have a demonstrated successful performance under stressful conditions. The comparison group that comes to my mind is mechanical engineers. On the whole, the mechanical engineering profession keeps this country running and progressing. Mechanical engineering seems to attract about the right number of people to keep up with the demands of industry. The quality and preparation of mechanical engineers is adequate for industry purposes.
Mechanical engineers have to master many skills and have a wide range of knowledge.
They must learn new skills at a steady pace keep up with ever changing jobs. These professionals must work with others that are not of their choosing to produce a product to the specifications set externally under the pressures of deadlines and budgets. They are very practical problem solvers. I am not saying that the people who now go into mechanical engineering would necessarily make adequate teachers. However, the level of skills and performance is similar to what we demand of teachers.
