Parsons' theory has been worked and reworked by sociologists to try to take into account the variations not accounted for in the Sick Role Theory. Parsons wrote what many plain folks already upheld: if you are sick, you aren’t to blame and you don’t have to work if you try to get well and obey your doctor, nurse, pharmacist, etc.
Here is the seed of the authority we have been searching for in this piece: an apparent bargain between society tolerating the sick so long as the sick respond by respecting our authority and being obedient. But, this Theory presupposes that the ill will recover and that the process will be a finite one, not an enduring one.
Frustration with a never-ending illness creates a variety of responses, among them the urge to scapegoat. The chronically ill/disabled are unable to 'fix' themselves and must continue in their status as ill/disabled, making them vulnerable to scapegoating. The "everything would be OK if you..." or "the only thing you are concerned about is yourself" position creates a designation for the chronically ill/disabled impossible to escape. In place of support, all support of an emotional nature is suddenly withdrawn... it can be damaging for all concerned.
