I don't think the Couches are as wealthy as they have been painted. They are comfortable, but rich? I guess that is relative, so relatively speaking, in North Texas terms, they don't appear to be so rich that they can buy off LE and judges.

These are nice homes, of course. But compared to Dallas area "wealthy," they are dated, not located in prestigious areas, and not particularly impressive. For someone who thinks they are really impressive, it's not really congruent with reality.
