The state must be the one and only non-profit organization in the state!

Check this out:

 A non-profit organization (abbreviated as NPO, also known as a not-for-profit organization^[1]) is an organization that does not distribute its surplus funds to owners or shareholders, but instead uses them to help pursue its goals.^[2] Examples of NPOs include charities (i.e. charitable organizations), trade unions, and public arts organizations. Most governments and government agencies meet this definition, but in most countries they are considered a separate type of organization and not counted as NPOs. They are in most countries exempt from income and property taxation.
