Sufficiency Economy is neither a theory nor a policy, but a philosophy that can help guide the behavior of individuals, households, organizations or government. sufficiency economy philosophy is distilled from His Majesty the King’s experiences of development work, combined with observations of people’s behaviors around the country as they have grappled with the challenges of the development process. Thus, the applications of sufficiency economy philosophy appear in various forms, and the insights gained from one group can be applied to other groups of people, both in the modern urban or rural sectors.
