This interview, condensed and edited for style and clarity, discusses the current state of libertarian ideas and the broader movement. Reflecting on nearly five decades in the libertarian movement, Boaz notes an increase in libertarian intellectuals and ideas compared to the past. He highlights the importance of the nonaggression principle as the essence of libertarianism, emphasizing freedom of speech, religion, property, and markets within a framework of cosmopolitanism and tolerance. Boaz also reflects on the founding of the Cato Institute in 1977 and its early focus on issues like Social Security, school choice, and foreign intervention. He discusses the progress made on free trade, human rights, civil rights, and deregulation, while acknowledging challenges like the difficulty of rolling back entrenched programs like Social Security. Boaz shares his evolving attitude towards Ronald Reagan, noting that while he supported Reagan in the 1970s, as a libertarian, he was critical of many of Reagan’s policies during his presidency. He suggests that libertarians may have become nostalgic for the Reagan-Thatcher era as a time when leaders articulated libertarian rhetoric.
