FROM 1967 UNTIL THE REFERENDUM, THE DEBATE ON THE COMMON Market in Britain produced a vast amount of literature devoted to the economic, political and social ramifications of joining. The main economic issues debated were the cost of entry and its effect on Britain's balance of payments, prices and the standard of living. The other problems centred around the tax system, including VAT, the flow of capital, unemployment, technological development, the value of the pound, the Community's agricultural policy, its regional policy, the volume of exports and labour mobility. In the social field the main concern was the standard of the social services, especially the National Health Service. In the political field debate centred around the undemocratic and bureaucratic nature of the EEC decision-making system; Britain's sovereignty, especially as regards the ability of Parliament to pursue independent economic, social and foreign policies; the connections between Britain and the Cornmon wealth, EFTA, the USA, Eastern Europe and developing countries. In addition the Treaty of Rome itself and the ideological, social and political nature of the Communities were debated.
