I think that the "Epstein class" qualifies as a class because although the Epstein ring is a group of collaborators, when I say "Epstein class" I *think* people understand I'm also including the other pedophile billionaires and millionaires that surely exist, who often do things out of class solidarity with each other.
In fact, I'm sure some of the people in Epstein's emails actually were innocent of literal child rape, but to be "part of the club" and get grants or just access to influential figures they cozied up and looked the other way at a literal conviction for sex trafficking. The way they discuss things like the MeToo movement shows a perverse kind of solidarity, for example, and I'm sure others not even in their orbit but who are similarly rich/influential + patriarchy fans have a default sympathy for these people every time one gets outed. They do things like write/sponsor op-ed pieces talking about how MeToo has gone too far or quietly drag their feet on discrimination investigations in their own institutions, etc. Things that influence our entire society to be more conducive to their evil as a class, not just as individuals.
I think perhaps explaining that, which a wide variety of people will agree with, is the start of a conversation that can then turn to "Epstein is a symptom, not a cause. Let me explain how patriarchy and capitalism ensure that even once he dies, not only are his collaborators not held accountable, but *another* Epstein will inevitably surface.
Along the way you gotta (as you rightly point out) be careful of the tendency to blame this on "the Jews" or another group of people rather than a system, but I think starting from the widely acknowledged ongoing travesty of justice and working towards a systemic explanation could be more successful than starting with systems.
