Hooks notes that both Friedan and her book are symbolic of the problems in perspective embodied in the movement from its earliest days to the present.... that being that it is essentially a movement of upper middle class white women grounded in a discontent that in essence is as sexist, imperialistic and capitalistic as the system it's trying to change.
