Emerson argues that prices and economic activity are most reliably regulated through the interaction of demand and supply rather than extensive government intervention. By calling this relationship a “self-adjusting meter”, he presents the market as a mechanism that responds to changing wants, scarcity and availability without requiring constant external direction.

Within Wealth, the statement forms part of a broader argument for economic non-interference, equal laws and protection of property. Emerson is expressing a 19th-century liberal view of political economy in which competition and individual initiative are expected to distribute resources effectively. The claim is philosophical and economic rather than an established rule applying equally in all circumstances. Modern economies often combine market mechanisms with regulation where governments seek to address issues such as monopoly, external costs, public goods or unequal access to opportunity.

“Wealth brings with it its own checks and balances. The basis of political economy is non-interference. The only safe rule is found in the self-adjusting meter of demand and supply. Do not legislate. Meddle, and you snap the sinews with your sumptuary laws. Give no bounties: make equal laws: secure life and property, and you need not give alms. Open the doors of opportunity to talent and virtue, and they will do themselves justice, and property will not be in bad hands. In a free and just commonwealth, property rushes from the idle and imbecile, to the industrious, brave, and persevering.”
