Protestants, hell and profession

Thanks again Henry and John for your answers,

Regarded to the analysis of  Max Weber, do you think that the
idea of vocation (profession) can be interpreted in calvinist doctrin as a
predestination to heaven or to hell (symbolic or economical success) in the
work we are called to develop? If some are predestinated to develop certain
works (let´s say: to  write), and some are predestinated to wash water
closets, God would legitimate division of work. God then would be very alike
to Adam Smith? In both cases rationality is predetermined.
