Dead middle-of-the-band for US household income, in Mississippi (particularly historically) makes you the scion of a posh suburb indeed. Note that a common characteristic of people of unusual means relative to their locality is that they insist that they're average; in-and-of-itself, it's not convincing.
I think my point still stands, regardless. No one has yet explained how they know that consultants make up the bulk of supercommuters.
