Unchosen callings breed aversion and evasion, harming social efficiency

Evidence

The division of labour brought about by the caste system is not a division based on choice. Individual sentiment, individual preference, has no place in it. It is based on the dogma of predestination. Considerations of social efficiency would compel us to recognise that the greatest evil in the industrial system is not so much poverty and the suffering that it involves, as the fact that so many persons have callings which make no appeal to those who are engaged in them. Such callings constantly provoke one to aversion, ill will and the desire to evade. — Ambedkar, B R, Annihilation of Caste_ The Annotated…, 861
