This topic is worthy and deserves to be discussed in detail. Let me give the following quotes.

"In reality the difference of natural talents between individuals is much less than supposed. These dispositions so different, which seem to distuingish the men of different professions when they arrive at mature age, are not so much the cause as the effect of division of labour." - ADAM SMITH.
 
"In principle a porter differs less from a philosopher than a mastiff does from a greyhound. It is the division of labour which has placed an abyss between the two." -KARL MARX
