The Legislature declares that: The disorderly marketing of commodities in this state; the improper preparation for market; the lack of uniform grade specifications or uniform inspection of commodities; the marketing of commodities in excess of reasonable or normal market demands therefor; or the inability of individual producers to expand existing markets or to develop new or larger markets for California grown commodities tends to prevent agricultural producers from maintaining a proper standard of living or from contributing their fair share to the support of necessary governmental and educational functions and thereby tends to increase unfairly the tax burden of other citizens of this state.
