"This resentment often falls into one of two categories, either "I don't know how to do this myself" (which is the lack of expertise) or "I don't want to do this so I'll hire someone" (which often is associated with the "this work is beneath me, I can't believe these people charge this, I guess I'll have to pay" idea)." You're missing the big one - "I'm sure this guy is bilking me, but I can't prove it." The analogy for the original author would be "This guy's full of it and motivated more by ideology than he admits". It's interesting that the other experts he references are lawyers, doctors and engineers. It might be highly unlikely that a layman would contradict a lawyer, doctor or engineer and come to the right conclusions for the right reasons. This is less the case for the softer sciences such as the author's field of social policy.
