UCGal had a good point on the specifically trained math/physics teacher but the arguement to me was the differences in the difficulties of the circulum. Math teachers stand out and that is why they are paid a differential (at least in Vegas they are don’t know about here).
But I was not arguing about the engineers getting higher rates for stress. That is part and partial to our gig.
However I do think we should pay teachers better for stress. The stress of what they do is rough. Also better pay would attract better talent into the field but with that bar should be raised.
In general, the greater the stress or risk, the more we reward a position (and I mean any occupation).
