Previous rent-seeking research correlates the aggregate power of multi-sector pressure groups with income inequality among the American states. Other research correlates the intra-sector power of specific economic interests with economic development pathologies. Several studies conclude that the legal sector is a rent-seeking interest that generates development pathologies such as lower rates of growth and, possibly, economic bias. No previous study systematically compares the separate roles of multi-sector pressure groups versus the legal sector as predictors of income inequality. This research documents the importance of legal sector power as an autonomous predictor of income inequality.
