(a)
The marketing program will tend to reestablish or maintain such level of prices for the commodity as will provide a purchasing power for the commodity which is adequate to maintain in the business of producing the commodity such number of producers as is required to provide such supply of the quantities and qualities of the commodity as is necessary to fulfill the normal requirements of consumers.
(b)
The marketing program will tend to approach such equality of purchasing power at as rapid a rate as is feasible in view of the market demand for the commodity.
(c)
The marketing program conforms with the provisions of this chapter and will tend to effectuate the declared purposes and policies of this chapter.
(d)
The marketing program will protect the interest of consumers of the commodity through the exercise of the powers of this chapter only to such an extent as is necessary to establish the level of purchasing power which is described in subdivision (a) of this section.
