- IDEA 1 OF 8
Look at all the effects
Hazlitt's one lesson is that good economics looks at the long-term effects of a policy on all groups, not just the short-term effects on one group.
Many bad policies, he argues, come from ignoring the hidden consequences.
- IDEA 2 OF 8
A broken window creates no wealth
Hazlitt retells the story of a broken shop window.
Some say it helps the glazier, but Hazlitt points out that the shopkeeper now cannot spend that money on something else. Destruction does not create real wealth.
- IDEA 3 OF 8
Public works have hidden costs
Government projects create visible jobs, but Hazlitt argues that the taxes paid for them reduce spending and jobs elsewhere.
These unseen losses are often forgotten. The bridge is seen; the lost jobs are not.
- IDEA 4 OF 8
Taxes discourage production
Hazlitt argues that high taxes reduce people's incentive to work, save and invest.
This can lower production and harm the economy over time. Effort is discouraged when rewards are taxed away.
- IDEA 5 OF 8
Machines create new jobs
Many fear that machines destroy jobs.
Hazlitt argues that machines lower costs and prices, which increases demand and creates new jobs in the long run. Fear of machines is understandable but misplaced.
- IDEA 6 OF 8
Tariffs help few, hurt many
Tariffs protect some industries, Hazlitt explains, but they raise prices for consumers and harm other industries.
The benefits are visible, while the costs are spread widely. Everyone pays a little more.
- IDEA 7 OF 8
Price controls cause shortages
When governments fix prices below market levels, Hazlitt argues, shortages follow.
Producers have less reason to supply goods, and consumers cannot buy what they want. Black markets often follow. Quality also falls.
- IDEA 8 OF 8
Minimum wages can reduce jobs
Hazlitt argues that setting wages above what workers' output is worth can lead to unemployment, especially for less-skilled workers.
He presents this as an unintended consequence. Good intentions can backfire.
