At the present moment, there are so many countries, they can produce profuse quantity of food grain. Sometimes they do it and throw it in the ocean for economic, what is called, balance. This is not good. Everyone should produce enough quantity of food grains, and if there is shortage, they should send there. Send there. In this way, the whole world should cooperate. There is United Nation, but what they are doing? Let them study Bhagavad-gītā how to make United Nation. That will be perfect. Not these short-sighted men with politics and diplomacy within the heart, they can bring all the nations united. That is not possible. Let them discuss Bhagavad-gītā. Let them discuss how perfect society can be established. Then there will be peace. And vaiśya-karma svabhāva-jam.
And paricaryātmakaṁ karma śūdrasyāpi svabhāva-jam (BG 18.44). And those who are not intelligent, to be trained up as a brahmin or a kṣatriya or a vaiśya, the fourth-class men, let them work these three other classes. Let them work. Paricaryātmakaṁ karma śūdrasyāpi svabhāva-jam. In this way the human society should be divided into four divisions, they should cooperate, and they should be trained up. Not a single man should remain unemployed. He must be engaged in some employment as a brāhmaṇa, as a kṣatriya, as a śūdra or as a vaiśya. Otherwise, idle brain will be devil's workshop. Therefore, in spite of so much educational propaganda in the Western countries, the young men are coming to become hippies. Because there is no proper training. Here is the hint, Bhagavad-gītā gives you. You train the students in that way, then there will be perfect society.
