public goods
Collective societal benefits
Public goods are resources or services that remain available to all regardless of who pays for them—one person's use doesn't diminish another's access.
National defense, street lighting, and clean air are classic examples.
The concept is central to economics and political philosophy, explaining why markets alone won't provide certain necessities: no one can be excluded from benefiting, so no one has incentive to pay.
Public goods require collective funding through taxation.
