QUOTE : Unions, as we have seen, pushed for and won legislation that legitimized collective bargaining. Small farmers got federal price supports and a voice in setting agricultural policy. Farm cooperatives, like unions, won exemption from federal antitrust laws. Small retailers obtained protection against retail chains through state “fair trade” laws and the federal Robinson-Patman Act, requiring wholesalers to charge all retailers the same price regardless of size and preventing chains from cutting prices.
