Well, your barber is an expert on hair.

  Well, if you really want to drill down on this example: the barber doesn't have substantial interests in which type of haircut you get. Tesla has substantial interest in which kind of carbon tax you get -- high carbon tax would be a boon. Doesn't materially effect how good an idea carbon taxes are, though. Also, do people ask their barber what haircut they should get? I have only ever done a buzz cut or given a description / picture.

    A proper analogy would be a barber asking for a tax on long hair. Yeah, he would have to find someone to cut his own hair too.

    There's a joke/aphorism, "that's like asking your barber if you should get a haircut." Apparently it's not as well-known as I thought.

  I haven't seen anything to suggest he is an expert in macro-economic forecast modelling. Just because I know how to use a command line doesn't equate to me being an expert in running an IT company. It's not the best analogy but Musk is pretty far removed from what most economists actually do.

    Yes, though on this particular matter he's just agreeing with what has been the consensus amongst economists for a long time.
