If i may take your word for it then from what you say :

1) It does NOT follow from the data that "income drops at and beyond
the Ph.D level".

2) What does follow (as you yourself indicate) is that
       a) salaries in academics are lower than in industry
       b) there is a concentration of the highly educated in academics
rather than industry
       c) hence "average" salaries of the highly educated are lower
than that of other people of
           say the same age (what else ?) elsewhere. (Actually even
this does not follow from
           the data since there is no indication if comparison was
done in the same age
           group. Besides was the non academic group a random
selection from the population
           or was it selectively CEOs of industry who didn't have a
Ph.D. Do you see what I am
           getting at ?)

To demonstrate that income drops at and beyond the Ph.D level a
statistician would have to
compare "average" salaries of Ph.Ds in industry with other levels of
education in industry (or
for that matter in academics).

1) and 2) above are two different conclusions !
