I doubt many ATPs toiled as long for their rating as long as
candidates for doctorates have in the halls of academia. But it does
take different skill sets in most cases, doesn't it?

The important point is that the knowledge gap between an average ATP and
an
average non-pilot is far smaller than the gap between someone with a PhD
in
chemistry and someone with no special knowledge of chemistry.

How can you possibly quantify something like this?
