Srila Narottama dasa Thakura says:

Lord Caitanya Mahaprabhu delivered the two fallen brothers Jagai and Madhai, but the entire world is presently full of Jagais and Madhais, or, in other words, woman-hunters, meat-eaters, gamblers, thieves and other rogues, who create all kinds of disturbance in society. The activities of such persons have now become common practices. It is no longer considered abominable to be a drunkard, woman-hunter, meat-eater, thief or rogue, for these elements have been assimilated by human society. That does not mean, however, that the abominable qualities of such persons will help free human society from the clutches of maya. Rather, they will entangle humanity more and more in the reactions of the stringent laws of material nature. One's activities are all performed under the influence of the modes of material nature (prakrteh kriyamanani gunaih karmani sarvasah). Because people are now associating with the modes of ignorance (tamo-guna) and, to some extent, passion (rajo-guna), with no trace of goodness (sattva-guna), they are becoming increasingly greedy and lusty, for that is the effect of associating with these modes. Tada rajas-tamo-bhavah kama-lobhadayas ca ye: "By associating with the two lower qualities of material nature, one becomes lusty and greedy." (Bhag. 1.2.19) Actually, in modern human society, everyone is greedy and lusty, and therefore the only means for deliverance is Sri Caitanya Mahaprabhu's sankirtana movement, which can promote all the Jagais and Madhais to the topmost position of sattva-guna, or brahminical culture.

At present, human society is specifically cultivating the mode of ignorance (tamo-guna), although there may also be some symptoms of passion (rajo-guna). Full of kama and lobha, lust and greed, the entire population of the world consists mostly of sudras and a few vaisyas, and gradually it is coming about that there are sudras only. Communism is a movement of sudras, and capitalism is meant for vaisyas. In the fighting between these two factions, the sudras and vaisyas, gradually, due to the abominable condition of society, the communists will emerge triumphant, and as soon as this takes place, whatever is left of society will be ruined. The only possible remedy that can counteract the tendency toward communism is the Krsna consciousness movement, which can give even communists the real idea of communist society. According to the doctrine of communism, the state should be the proprietor of everything. But the Krsna consciousness movement, expanding this same idea, accepts God as the proprietor of everything. People can't understand this because they have no sense of God, but the Krsna consciousness movement can help them to understand God and to understand that everything belongs to God. Since everything is the property of God, and all living entities-not only human beings but even animals, birds, plants and so on-are children of God, everyone has the right to live at the cost of God with God consciousness. This is the sum and substance of the Krsna consciousness movement.
