case. Ronald Inglehart and Christian Welzel contend that the realization of democracy is not based solely on an expressed desire for that form of government, but democracies are born as a result of the admixture of certain social and cultural factors. They argue the ideal social and cultural conditions for the foundation of a democracy are born of significant modernization and economic development that result in mass political participation. Randall Peerenboom explores the relationships among democracy, the rule of law and their relationship to wealth by pointing to examples of Asian countries, such as Taiwan and South Korea, which have successfully democratized only after economic growth reached relatively high levels and to examples of countries such as the Philippines, Bangladesh, Cambodia, Thailand, Indonesia and India, which sought to democratize at lower levels of wealth but have not done as well. Adam Przeworski and others have challenged Lipset's argument. They say political regimes do not transition to democracy as per capita incomes rise. Rather, democratic transitions occur randomly, but once there, countries with higher levels of gross domestic product per capita remain democratic. Epstein et al. (2006) retest the modernization hypothesis using new data, new techniques, and a three-way, rather than dichotomous, classification of regimes. Contrary to Przeworski, this study finds that the modernization hypothesis stands up well. Partial democracies emerge as among the most important and least understood regime types. Daron Acemoglu and James A. Robinson, in their article "Income and Democracy" (2008) further weaken the case for Lipset's argument by showing that even though there is a strong cross-country correlation between income and democracy, once one controls for country fixed effects and removes the association between income per capita and various measures of democracy, there is "no causal effect of income on democracy." In "Non-Modernization" (2022), they further argue that modernization theory cannot account for various paths of political development "because it posits a link between economics and politics that is not conditional on institutions and culture and that presumes a definite endpoint—for example, an 'end of history'." Sirianne Dahlum and Carl Henrik Knutsen offer a test of the Ronald Inglehart and Christian Welzel revised version of modernization theory, which focuses on cultural traits triggered by economic development that are presummed to be conducive to democratization. They find "no empirical support" for the Inglehart and Welzel thesis and conclude that "self-expression values do not enhance democracy levels or democratization
