I like David Frum more and more. He’s a great example of a thinking conservative.
There are two big reasons today’s right loves the Austrians. One is that Austrian economists reject empirical analysis, and instead believe that you can reach conclusions about correct economic policies from a priori principles. It’s philosophy dressed up as economics; with the Austrians, there is never any risk that real-world events will interfere with your ideology.
In other words, if you adhere to Austrian experience-prone economic thinking, you’ll never be proven wrong and thus you’ll never have to defend your flawed theory, even when faced with the failure of free-market economics leading up to 2008 crisis.
