The art of economics consists in looking not merely at the immediate but at the longer effects of any act or policy it consists in tracing the consequences of that policy not merely for one group but for all groups.

Henry Hazlitt (1894–1993), an American journalist and popularizer of classical-liberal economics, used this formulation to summarize what he saw as the central discipline of economic reasoning. It appears in the opening chapter of his best-known book, written in the aftermath of the Great Depression and World War II, when governments were expanding economic planning, price controls, and interventionist policies. Hazlitt’s aim in that book was pedagogical: to equip general readers to evaluate policy proposals by following their ripple effects through time and across society, rather than being persuaded by immediate, visible benefits to a favored constituency.

Hazlitt argues that sound economic analysis is essentially a method: extend your view beyond the first, most obvious result of a policy and beyond the group that benefits most visibly. Many interventions create concentrated, immediate gains (often easy to publicize) while dispersing costs across other groups or into the future (often harder to notice). The quote encapsulates an opportunity-cost and general-equilibrium sensibility: policies must be judged by their full chain of consequences, including unintended effects. It also functions as a warning against “one-step” thinking—treating the seen effect as the whole story—and against special pleading for a single class, industry, or interest group.

2) “The whole of economics can be reduced to a single lesson… to look not merely at the immediate but at the longer effects… not merely for one group but for all groups.”
