There are a lot of ways to look at this.

First, there are a lot of people out there that just want to inspect homes, and NOT do marketing, answering phone, or paperwork. They just want to do the work.
Second, since it is the companies liability at stake, it is not unreasonable to think that someone else may look at the reports, and maybe make changes, especially if the inspector is new. Now before you all start jumping around, i'm not talking about making changes to sugar coat, or alter the basic observation. I'm talking about correcting something in the wording, or correcting something that was incorrect. Example, a new inspector of mine once put that plastic pipe was not allowed to be used on HOT water. Well, it was CPVC.
Third, a lot of inspectors have no idea what their true costs are to run the business, and only look at the inspection fee. Once you take the overhead out, pay the inspector a salary or percentage, there may not be a lot left as profit.
Unless you have had employees, most of you have very little idea of the hidden costs involved with multi inspector firms. And there are a bunch of hidden costs. It's just not as simple as A-B= C. Its more like A - B - z- y - w - x = C.
