The importance of social trust has become widely accepted in the social sciences. A number of explanations have been put forward for the stark variation in social trust among countries. Among these, participation in voluntary associations received most attention. Yet there is scant evidence that participation can lead to trust. In this article, the authors examine a variable that has not gotten the attention it deserves in the discussion about the sources of generalized trust, namely, equality. They conceptualize equality along two dimensions: economic equality and equality of opportunity. The omission of both these dimensions of equality in the social capital literature is peculiar for several reasons. First, it is obvious that the countries that score highest on social trust also rank highest on economic equality, namely, the Nordic countries, the Netherlands, and Canada. Second, these countries have put a lot of effort in creating equality of opportunity, not least in regard to their policies for public education, health care, labor market opportunities, and (more recently) gender equality. The argument for increasing social trust by reducing inequality has largely been ignored in the policy debates about social trust. Social capital research has to a large extent been used by several governments and policy organizations to send a message to people that the bad things in their society are caused by too little volunteering. The policy implications that follow from the authors' research is that the low levels of trust and social capital that plague many countries are caused by too little government action to reduce inequality. However, many countries with low levels of social trust and social capital may be stuck in what is known as a social trap. The logic of such a situation is the following. Social trust will not increase because massive social inequality prevails, but the public policies that could remedy this situation cannot be established precisely because there is a genuine lack of trust. This lack of trust concerns both “other people” and the government institutions that are needed to implement universal policies.

3 The number of articles published in scientific journals with “trust” as a keyword or in its abstract increased from 129 to 1,956 from 1990 to 2005. Adding the word “growth” to “trust” shows an increase from 1 to 42 articles, which indicates a stark increase in the use of this concept by political economists; ISI Web of Knowledge, http://www.isinet.com/.

7 There is a huge discussion in political philosophy of how to define “equality of opportunity.” It is certainly hard to imagine a society that would, in reality, create equal opportunity for all its citizens. We employ here a narrow definition that focuses on the establishment of public policies that are intended to create equal conditions for citizens regardless of their income, ethnic/religious background, sex, and race in areas such as health care, education, and social security and legal protection (“equality before the law”). Thus, central to our conceptualization of “equality of opportunity” is not whether there is “equality of opportunity” in general but whether the state does (or does not) promote equality of opportunity.
8 In theory, one could imagine a society with huge economic inequality but with perfect equality of opportunity. In practice, it seems as if these two types go together. For example, in contrast to the United States, the Nordic states provide all citizens who qualify for college with tuition-free education and provide benefits like universal health care and elderly care. One measure of the equality of opportunity is the level of educational inequality in a country. Using a measure of the standard deviation of educational attainment provided by Daniel Lederman of the World Bank, we found a modest correlation (r =.367, N = 62) with the Gini index of economic inequality. The correlation is attenuated by greater economic inequality than predicted for African and Latin American countries and lower economic equality than expected for countries in the Indian subcontinent. We found almost identical results using a Gini index of educational inequality (r =.364, N = 55) estimated by Vinod Thomas, Yan Wang, and Xibo Fan, “Measuring Economic Inequality: Gini Coefficients of Education” (Washington, D.C.: World Bank Institute, Office of the Vice President, and Economic Policy and Poverty Reduction Division, January 2001).

20 This is not an issue of case selection, since we get an R2 of.560 of the regression of the Galbraith measure on trust for the thirty cases with nonmissing values on both Gini coefficents.
21 The R2 for the 1963 measure with levels of trust in the 1990s is.653 (N = 33) compared to.560 for the 1996 index of inequality. The regression coefficients (.022 and.020, respectively) are almost identical.

63 This is how the agents of the time, both union leaders and the leaders from the employers' federation, described what happened in the mid-1930s; see Rothstein, Bo, Social Traps and the Problem of Trust (Cambridge: Cambridge University Press, 2005)CrossRefGoogle Scholar, chap. 7. Of particular importance was that the leaders of the Social Democratic Party could make “credible commitments” toward the Employers' Federation that they would not use their political power over the state administration to favor the union side, for example, in labor disputes.

97 If we had a choice, governments in high inequality/low social trust societies should opt for highquality universal education programs. There are several reasons for this. One is that universal public education both creates a sense of equal opportunity and generates more economic equality. Second, it should give parents a sense of optimism for the future or their children, and since optimism is strongly connected to social trust, this would have positive effects. Third, such programs would bring children and young people from different ethnic, religious, and social groups together. Results from social psychology show that this is one important generator of social trust; Yamagishi, Toshio, “Trust as a Form of Social Intelligence,” in Cook, K.
