Hankering does not give happiness
In the mode of passion, people become greedy, and their hankering for sense enjoyment has no limit. One can see that even if one has enough money and adequate arrangements for sense gratification, there is neither happiness nor peace of mind…If one wants happiness at all, his money will not help him…When one is engaged in the mode of passion, not only is he mentally unhappy, but his profession and occupation are also very troublesome. He has to devise so many plans and schemes to acquire enough money to maintain his status quo. This is all miserable. (Bg. 14.17)
Human civilizations should depend on the production of material nature without artificially attempting economic development to turn the world into a chaos of artificial greed and power only for the purpose of artificial luxuries and sense gratification. This is but the life of dogs and hogs. (Bhag 1.10.4)
Greed, Godlessness, and Scams
A godless man is invariably greedy, angry, and fraudulent. Such a man can earn his livelihood by any means, black or white. (Bhag 1.14.3)
The difference between a pious man and a criminal is that one is pure in heart and the other is dirty. This dirt is like a disease in the form of uncontrollable lust and greed in the heart of the criminal. Today people in general are in this diseased condition, and thus crime is very widespread. When the people become purified of these dirty things, crime will disappear. The simplest process of purification is to assemble in congregation and chant the holy names of God. This is called sankirtana and is the basis of our Krishna consciousness movement.

Corruption and Politics
But in the age of Kali, the executive heads of state will be indifferent to such religious principles, and therefore under their patronage the opponents of religious principles, such as greed, falsehood, cheating, and pilfery, will naturally follow, and so there will be no meaning to propaganda crying to stop corruption in the state. (Bhag 1.17.32 )
Due to their greed for material position, they falsely present themselves as leaders before the people and collect their votes, although they are completely under the grip of the laws of material nature. (Bhag 4.24.66)
Purification of the heart
The more a person is freed from lust, anger and greed, the more his existence becomes pure. (Bg. 16.22)
The whole world is revolving due to kama and lobha. Kama means “lusty desire,” and lobha means “greed.” People cannot have enough sex or money, and because of this, their hearts are filled with contaminations, which have to be cleansed by hearing, repeating, and chanting. Human life is meant to get rid of anarthas, unwanted things, but where is the university or college where this science of purification is taught? The only institution is this Krishna consciousness society. Krishna is within the heart, and the contaminations are also there, but Krishna will help us cleanse them. Nasta-prayesv abhadresu nityam bhagavata-sevaya (Bhag. 1.2.18). We must regularly hear Srimad-Bhagavatam and chant Hare Krishna; these are the two processes recommended by Caitanya Mahaprabhu.
(Teachings of Lord Kapila, the Son of Devahuti)
The only process that will purify the mind is to engage it in Krishna… If we engage our mind in Krishna, naturally the consciousness becomes fully purified, and there is no chance of the entrance of material desire and greed. (Bhag. 3.25.16)
