How Does Adam Smith’s ‘Invisible Hand’ Work?

TL;DR

The "invisible hand" is Adam Smith's metaphor for the unintended social benefits resulting from individual self-interested actions in a free market.
Smith's ideas, particularly specialization and self-interest, challenged the prevailing mercantilist economic system of his time.

Critics like Karl Marx argued that the invisible hand was an outdated system, and government control could better serve societal needs.
Friedrich A. Hayek argued that centralized economic planning is impossible due to the decentralized nature of knowledge, advocating for free markets to efficiently allocate resources through price signals.
