Not the guy you replied to, but at least around here usually people aren’t criticizing Biden from abandoning the working class, because as you just said he didn’t; he was pretty good for the working class. (The majority of) people here are criticizing Biden for being weak on Trump and for supporting Israel’s genocide, and as a completely separate issue criticizing the DNC for actively abandoning the working class in the election. People who are saying Biden didn’t do anything for the working class need to hear this, but I’m pretty sure that’s not what the person you’re responding to is saying.
