"Buchanan began working on a description of power that started out as a critique of how institutions functioned in the relatively liberal 1950s and ‘60s, a time when economist John Maynard Keynes’s ideas about the need for government intervention in markets to protect people from flaws so clearly demonstrated in the Great Depression held sway. Buchanan, MacLean notes, was incensed at what he saw as a move toward socialism and deeply suspicious of any form of state action that channels resources to the public. Why should the increasingly powerful federal government be able to force the wealthy to pay for goods and programs that served ordinary citizens and the poor?
In thinking about how people make political decisions and choices, Buchanan concluded that you could only understand them as individuals seeking personal advantage. In an interview cited by MacLean, the economist observed that in the 1950s Americans commonly assumed that elected officials wanted to act in the public interest. Buchanan vehemently disagreed — that was a belief he wanted, as he put it, to “tear down.” His ideas developed into a theory that came to be known as “public choice.”
Buchanan’s view of human nature was distinctly dismal. Adam Smith saw human beings as self-interested and hungry for personal power and material comfort, but he also acknowledged social instincts like compassion and fairness. Buchanan, in contrast, insisted that people were primarily driven by venal self-interest. Crediting people with altruism or a desire to serve others was “romantic” fantasy: politicians and government workers were out for themselves, and so, for that matter, were teachers, doctors, and civil rights activists. They wanted to control others and wrest away their resources: “Each person seeks mastery over a world of slaves,” he wrote in his 1975 book, The Limits of Liberty."
