The brāhmaṇa class or intelligent class is working in one way, the kṣatriya or administrative class is working in another way, and the mercantile class and the laborers are all tending to their specific duties. In the human society, whether one is a laborer, merchant, administrator or farmer, or even if one belongs to the highest class and is a literary man, a scientist or a theologian, he has to work in order to maintain his existence.

Bhagavad-gita As It Is
BG Preface and Introduction
BG Introduction:
Thus the Lord says that even a merchant, a fallen woman or a laborer or even human beings in the lowest status of life can attain the Supreme. One does not need highly developed intelligence. The point is that anyone who accepts the principle of bhakti-yoga and accepts the Supreme Lord as the summum bonum of life, as the highest target, the ultimate goal, can approach the Lord in the spiritual sky. If one adopts the principles enunciated in Bhagavad-gītā, he can make his life perfect and make a permanent solution to all the problems of life.
