“We see materialistic persons busily engaged in economic development all day and all night, trying to increase their material opulence, but even if we suppose that they get some benefit from such endeavors, that does not solve the real problem of their lives. Nor do they know what the real problem of life is. This is due to a lack of spiritual education.” (Shrila Prabhupada, Shrimad Bhagavatam, 7.6.4 Purport)
