In the human society there must be four divisions — the brahmana, the ksatriya, the vaisya and the sudra — according to the quality. The most intelligent class of men, they should become brahmanas. Satya, samah, damah, titiksa, arjavam, jnanam vijnanam astikyam brahma-karma svabhava-jam [Bg 18.42]. So the next-intelligent class of men should become the administrators, and the next-intelligent class men should be the productive class, vaisyas.

vaisya-karma svabhava-jam

Everything is there. And especially in India, this ideal life of human society should be inaugurated. We should not imitate the Western people, who are now dwindling. Their material civilization is no longer giving them happiness. That is a fact.
