Libertarianism is the philosophy that makes neoliberalism possible. They stand to each other in the relationship of a theory and the practice arising from the theory.
My own attitude to neoliberalism is that of an intelligent smoker to cigarettes. An intelligent smoker might love his cigarettes while also recognizing that they are very unhealthy. We’ve all known that one person who smoked two packs a day since 14 and is perfectly healthy at age 85. But we all know that this person is an outlier. She (it’s almost always a woman) probably has some genetic glitch that makes her immune to the harm of her habit. Much as she might love her ciggies, she won’t give a pack to a 5-year-old.
Libertarians, unfortunately, don’t understand the part about the glitch. They are almost invariably very brilliant, high-IQ, very organized people. Their fatal flaw is not realizing that almost nobody else is that way. Their ideas are deadly to those who don’t have their glitch. They want to distribute cigarettes, metaphorically speaking, to every 5-year-old. The neoliberal reality that libertarian philosophy engenders is fantastic for these glitchy (in a good way) people but deadly to everybody else. Libertarians are at war with human nature itself. Their theory appeals to the best qualities in human beings, and that makes it very attractive. But it makes no concessions for the irrational, emotional and dark side of humanity. And that’s why the results of their theory are so hellish when put into practice.
