• Thus, it is the growth of capital that fuels the progress of opulence in Smith's representation of The Nature and Causes of the Wealth of Nations.

Now we turn our attention directly to capital and the role it plays in the progress of opulence, the analysis Smith presents in Book II of his Wealth of Nations.
