Heaven has so decreed in the creation of man....

Humanity, like a great army, requires a general, captains, underofficers in their degree, and soldiers, each with their appointed duties.

Degrees are absolutely necessary to ensure an orderly organization.

An army could not be composed of generals alone, or of captains only, or of nothing but soldiers without anyone in authority.
Certainly, some being enormously rich and other lamentably poor, an organization is necessary to control and improve this state of affairs.

It is important to limit riches, as it is also of importance to limit poverty.
