I don't think Graham is being a status quo warrior here at all and I would have to reread carefully to see if he was really committing the naturalistic fallacy, I think that is an odd reading. I think his reasoning is fairly sound here. He actually laments that solving income inequality is very difficult, which it is. A lot of lip service is paid to this topic and usually all an politician has to say about it is something about manufacturing jobs.

I almost feel you may change the entire field of economics with committing the naturalistic fallacy under your reasoning ...
