But, as Andrew Skinner reveals in his introduction to this edition, the
real sophistication of "The Wealth of Nations" lies less in individual
areas of economic analysis than in its overall picture of a vast
analytical system--a capitalist economy--in which all the parts can be
seen simultaneously interacting with each other. In addition, Smith's
view of society was not merely an economic one. "The Wealth of Nations"
is far from being an apologia for unregulated business enterprise: Smith
was at pains to point out that economic advance can have undesirable
social consequences, and that labour which is economically unproductive
can be beneficial to society at large.
