Key passages
“It is not from the benevolence of the butcher, the brewer, or the baker that we expect our dinner, but from their regard to their own interest.”
We rely on the self-interest of others, not their kindness, to get what we need.
Smith illustrates how self-interest drives economic exchange, a key concept in his theory of the invisible hand.
“By pursuing his own interest he frequently promotes that of the society more effectually than when he really intends to promote it.”
When individuals act in their own self-interest, they often benefit society more than if they had tried to help society directly.
This introduces the invisible hand concept, showing how individual actions can lead to collective good without central planning.
