Mexico’s 2012 presidential election was fought between two affluent career politicians and a millionaire businesswoman. The 2013 race in Chile pitted an economist against a physician. And the top candidates in last year’s presidential election in Brazil were both millionaire economists. The pattern is clear: Latin American democracies – like democracies all over the world – are disproportionately run by the rich. Although working-class jobs (informal workers, manual labor, and service industry jobs) make up the vast majority of the labor force in every Latin American country, only a tiny percentage of Latin American lawmakers come from those kinds of jobs. Like most places, Latin America is run by white-collar governments. Many journalists, pundits, and political observers take this aspect of the governing environment for granted in Latin America and elsewhere. (In 2013, commentators in Chile buzzed about having two female frontrunners in the presidential race. But they failed to note that both came from affluent backgrounds.) Perhaps they are so accustomed to welloff politicians that they simply see them as a natural feature of the political landscape. Or perhaps they believe that it does not matter whether politicians are drawn from one class or another. In the 1970s, scholars of comparative politics reached exactly that conclusion. After a handful of studies (which, in hindsight, probably had serious methodological problems) found that policymakers from different classes behave about the same in office, the eminent political scientist Robert Putnam concluded that “the assumption of a correlation between attitude and social origin lies behind most studies of the social backgrounds of elites, . . . most of the available evidence tends to disconfirm this assumption” (R. Putnam, unpublished manuscript: 93). A decade later, a sweeping review of the evidence available in the mid-1980s concluded that the existing data were “scattered and inconclusive” and “certainly [did] not add up to a finding that the social . . . [or] economic . . . biases of legislative recruitment result in a . . . policy bias of legislative institutions” (Matthews 1985: 25). In the mid-1990s, another review of the research reached the same conclusion: scholars had “not clearly established that the social background of politicians has a significant influence on their attitudes, values and behavior” (Norris and Lovenduski 1995: 12). Ever since, the idea that a legislator’s class does not matter has been the de facto conventional wisdom in the scholarly community. This conventional wisdom has helped fuel indifference about the overwhelmingly unequal social class makeup of the world’s political institutions. But new evidence suggests that the scholarly consensus may be wrong (Carnes 2013, and his contribution to this Swiss Political Science Review 21(2): 229–236 doi:10.1111/spsr.12162
