The post-war consensus, sometimes called the post-war compromise, was the economic order and social model of which the major political parties in post-war Britain shared a consensus supporting view, from the end of World War II in Europe in 1945 to the late-1970s. It ended during the governance of Conservative Party leader Margaret Thatcher. The consensus tolerated or encouraged nationalisation, strong trade unions, heavy regulation, high taxes, and an extensive welfare state. The notion of a post-war consensus covered support for a coherent package of policies that was developed in the 1930s and promised during the Second World War, focused on a mixed economy, Keynesianism, and a broad welfare state. Historians have debated the timing of the weakening and collapse of the consensus, including whether it ended before Thatcherism arrived with the 1979 general election. They also suggest that the notion might not have been as widely supported as some claim, and that the word consensus might be inaccurate to describe the period. Embedded liberalism has been applied to describe the post-war consensus on a global stage, around the same period from World War II to the crisis of the 1970s, and contrast it with the paradigm shift led by neoliberalism that followed.
Origins of post-war consensus The thesis of post-war consensus was most fully developed by Paul Addison. The basic argument is that in the 1930s Liberal intellectuals led by John Maynard Keynes and William Beveridge developed a series of plans that became especially attractive as the wartime government promised a much better post-war Britain and saw the need to engage every sector of society. The foundations of the post-war consensus can be traced to the Beveridge Report. This was a report by William Beveridge, a Liberal economist who in 1942 formulated the concept of a more comprehensive welfare state in Great Britain. The report, in shortened terms, aimed to bring widespread reform to the United Kingdom and did so by identifying the "five giants on the road of reconstruction": "Want… Disease, Ignorance, Squalor and Idleness". In the report were labelled a number of recommendations: the appointment of a minister to control all the insurance schemes; a standard weekly payment by people in work as a contribution to the insurance fund; old age pensions, maternity grants, funeral grants, pensions for widows and for people injured at work; a new national health service to be established. The post-war consensus included a belief in Keynesian economics, a mixed economy with the nationalisation of major industries, the establishment of the National Health Service and the creation of the modern welfare state in Britain. The policies were instituted by all governments (both Labour and Conservative) in the post-war period. The consensus has been held to characterise British politics until the economic crises of the 1970s (see Secondary banking crisis of 1973–1975) which led to the end of the post-war economic boom and a brief and failed experiment with monetarist economics as championed by Milton Friedman. The roots of Keynes's economics, however, stem from critique of the economics of the interwar period depression. Keynes's style of economics encouraged a more active role of the government in order to "manage overall demand so that there was a balance between demand and output". It was claimed that in the period between 1945–1970 (consensus years) that unemployment averaged less than 3%, although the legitimacy of whether this was solely down to Keynes remains unclear. The first general election since 1935 was held in Britain in July 1945, giving a landslide victory for the Labour Party, whose leader was Clement Attlee. The policies undertaken and implemented by this Labour government laid the base of the consensus. The Conservative Party accepted many of these changes, and promised not to reverse them in its 1947 Industrial Charter. Attlee, using the Beveridge Report and Keynesian economics, laid out his plans for what became known as "The Attlee Settlement". The main areas he would tackle:
The mixed economy Full employment Conciliation of the trade unions Welfare Retreat from empire
Policy areas of consensus
