Tate Fegley surveys the big ideas of public choice—politics analyzed with the tools of economics—and shows where an Austrian approach sharpens them. Rational ignorance, concentrated benefits and dispersed costs, rent-seeking, the transitional gains trap, budget-maximizing bureaucracies, and the logic of collective action each get a turn, illustrated with sugar tariffs, million-dollar taxi medallions, and Sowell's Benedict Arnold thought experiment. Fegley's throughline: public choice is strongest when it drops the neoclassical assumptions of perfect knowledge and static equilibrium and grounds itself in Austrian subjectivism.
