Bénabou and Ok use expected utility to argue the prospect of upward mobility (POUM) may cause majority rejection of redistributive taxes that benefit the majority. They believe the poor are not risk seeking but instead believe they may soon be rich. In paid computerized experiments that allows redistribution the poor are risk seeking and the rich risk averse even though subjects play both roles. Changing risk attitudes with wealth levels is predicted by Kahnemann and Tversky (Econometrica 47(2):263–291, 1979). Rounds that mimic actual middle class decisions produce desired tax rates over 50% suggesting POUM is only a partial explanation for low taxes.
