All twelve principles

First principle

Property is a right—and a trust

Distributed ownership protects freedom; legitimate ownership also carries duties.

Property gives households independence, disperses power, permits planning, and transmits capital through generations. A society of owners is generally freer than a society of permanent tenants, whether the landlord is public, corporate, or financial.

Markets coordinate knowledge and reward useful enterprise, but they depend on trust, law, family stability, and public order that they cannot manufacture alone. The goal is a productive, property-owning, family-forming middle commonwealth—not equal outcomes or maximum consumption.
