(By me, this privileged Boomer who started out her adult life as an Ayn Rand libertarian and academic snob, dropped out of the middle class 25 years ago, and morphed into an extreme lefty anarchist via lived experience.)
Those of us who identify as members of the working classes need to cultivate our class solidarity/consciousness.
Any of us who already feel like we have that mind-set, then we need to expand out into those of our circles who identify as “liberal” but do not quite have class solidarity-consciousness.
Also we need to collect & support those of our fellow working-class folks who are truly inhabiting the most socio / economically marginalized rungs but are still trauma-identifying with the oligarchish class.
