No taxation, no democracy? Taxation, income inequality, and democracy

Does taxation promote democracy? Revisiting this question, I hypothesize that the effects of taxation on democracy tend to be relatively stronger in unequal societies because higher income inequality can amplify the extent to which citizens dissatisfied with higher levels of taxation want to soak elites. Using event history models to analyze a pooled time-series dataset of regime transitions that cover all countries from 1970 to 2000 if data are applicable, I find empirical evidence that taxation has a conditional impact on democratization, but not on democratic breakdown. According to the theory, higher taxation levels and greater income inequality should tend to promote democracy.
