This will, I know, bring flame upon my head. A favorite
construct employed by economists in analysis is "The
Economically Rational Man (Person)." The question posed is:
"What would an economically rational man (person), not subject
to any constraints, in full possession of the facts, do in X
situation." I believe that most economists would shake their
heads sadly and observe that persons who deliberately and out
of free choice _choose_ to enter and remain in employment
sectors where they know - or should know - that compensation has
been low, is low, and will doubtless continue to be low, are
simply acting economically irrationally. Perhaps there are
off-setting rewards. Or perhaps there are constraints . . .
such as being mathematically-challenged. After all, accountants
and engineers are paid better.
