Traces the development and practice of British politics from the late 19th century to the 1950s, highlighting the consolidation of government and economic production and consumption in the ‘collective era’. Beer first describes four premodern mindsets: old Tory (hierarchic, corporatist), old Whig (which transposed executive power to the cabinet), liberal, and Radical. The Enclosure Acts of the 1700s indicated the introduction of group politics (albeit aristocracy, the balanced constitution, and mercantilism remained dominant), in a long-term transition from patronage to party. In the 1800s, the primary distinction between liberals and Radicals lay in the theory of representation, one favoring liberty to act one’s conscience (the ‘masterless man’) and the other the ‘will of the majority’; Radical politics nonetheless incompletely utilized party to express class and ideological ends, according to later Socialists. The collective era, which reached its height in the 1950s, introduced or reified corporatist forms of a managed economy in combination with the welfare state. Beer then analyzes the workings of the Labour Party since the 1890s. Socialist doctrine held that party program reflects class interest, and all important decisions were to be taken before reaching Parliament. In 1907, the party formally voted itself power to instruct its MPs, although Radical views of the state’s role in alleviating evil and creating good persisted until the 1920s. The miners union’s joining the Trades Union Congress in 1909 was initially seen as a setback, until its commitment to nationalization during World War I. In 1917, Labour broke with David Lloyd George; in 1918 it committed to state ownership of the means of production, a which was unchallenged until 1951. Beer writes that Labour had to do so to differentiate itself after the ‘entente cordial’ with Liberals in 1907. On taking power as a minority government in 1929, Ramsay MacDonald faced the choice of ideology or pragmatism. Needing Liberal support, he along with Snowden, Thomas, Henderson, and Webb chose the latter. By 1931, absent a clear answer to the depression, MacDonald was forced to accede to 10 percent cut in unemployment benefits in order to win loans from New York banks. Allowed to play a large role in Churchill’s wartime government, Atlee executed the Socialist nationalization program over 1945-51; however, pressed by increasingly negative balance of payments and simultaneous demand for domestic goods, the party-government determined to steer workers into export trades or production of popular goods. The problem became closing the ‘manpower gap’ and reducing volatility of demand, finance being secondary. But after the TUC’s 1946 opposition to wage restraint, Hugh Dalton was replaced by Stafford Cripps, who returned from physical controls to market manipulation – a shift which included manufacturers accepting reduced prices and profits. The deal fell apart in 1950 (following 1949’s devaluation of sterling), at which time the unions asserted a measure of independence from Labour, in order to directly participate in collectivist bargaining. This was crucial in forging the new social contract, the paradigm of the managed economy, which Beer dates to 1940 (not 1945, because it was then workers accepted sacrifices to win the war). Henceforth, class was again not inherently political and determinist. In the 1950s, commitment to nationalization and its residual class image came to hurt Labour (Beer notes that 1/3 of the working class consistently voted Conservative throughout), presaging party change. The Fabians counterattacked but the Parliamentary leadership along with the TUC, which provided more than 50 percent of party revenue, prevailed. Turning to the Conservative party, Beer revisits the old Tory and Disraeli’s ‘Tory democracy’ mindsets: belief in hierarchy; that society is an organic unit with a traditional (not rational) social ethic; that politics isn’t the highest calling but rather is an obligation in service of society; that the governing class leads by virtue of talent; that voters choose leaders, not policy, because of the leadership’s being in tune with changing circumstances, tradition, interest groups, and of course electoral calculation. Thus, in the 1930s the less ideological, more adaptable Tories converted to monetary expansion, mercantilism, and industrial and agriculture ‘rationalization’, thereby abandoning gold and free trade. Tariff ‘reform’, headed by Chamberlain, was an important step toward the managed economy. Trade associations, rising in response to unions (and in contrast to US antitrust doctrine), were the gateway to producer group representation. By the 1950s, the Conservatives too were ready for collectivism, in which 1) the managed economy relied on bargaining with producer groups and 2) the welfare state accommodated consumer interests, as represented by party-government bidding for votes. In the collective era, government couldn’t be separated from production and consumption: ‘consumer sovereignty’ trumped popular sovereignty, Beer concludes. Yet differences remained: Labour focused on equality of outcomes, the Tories, who presumed inequality because of hierarchy, on distribution of power. Thus the question of morality – the just distribution of power to rule – persisted: voluntarism, the view that human wishes are the basis of legitimacy, conflicts with rationalism, a theory of fair ends. Apart from Beer’s framework, collectivism was upended by the reemergence of supply-side economics, that prices communicate demand and so the allocation of resources and rewards.
