Smith, as we have said, was not the proponent of any one class. He was a slave to his system. His whole economic philosophy stemmed from his unquestioning faith in the ability of the market to guide the system to its point of highest return. The market — that wonderful social machine — would take care of society's needs if it was left alone. "Consumption is the sole end and purpose of all production," he wrote.

Robert HeilbronerGrowth is the mantra of our society because the economy can't remain healthy without growth.Impregnable monopolies aside (and these are few), profits are both the hallmark of capitalism and its Achilles heel, for no business can permanently maintain its prices much above its costs. There is only one way in which profits can be perpetuated; a business-or an entire economy-must grow.
