[doktrin]

This is an infamous and reasonably well documented small group of people. You don’t need to speculate about their socioeconomic status because we know who they were and can count them on two hands.

TL;DR none of what you said remotely applies. They were middle-upper-class with access to resources and lived in Berkeley before moving to a notorious Concord safehouse in August ‘73, about 3 months before anything in this story takes place.
