Historically, much has been made of the so-called industrial revolution beginning circa 1750. But Srila Prabhupada calls this a revolution of the sudras: “The Industrial Revolution means revolution of the sudras. That is Industrial Revolution. Increasing the number of sudras. These scientists, they are also sudras. Because they have no real knowledge. Brahmana means one who has got real knowledge.” (Excerpted from a walk in Los Angeles, recorded on May 13, 1973 )
