public good

Collective societal resource

A public good is something that benefits everyone and can't be used up or restricted—clean air, national defense, street lighting.

Economists define it technically as non-rivalrous (one person's use doesn't diminish another's) and non-excludable (you can't prevent people from benefiting).

Public education is often defended as a public good.

More loosely, the public good means the general welfare of society: She devoted her career to the public good.
