This doesn't really answer the question, but I can see why you made that answer. Maybe I should have asked How they are better for workers? from the start
As per my argument to someone else, this can be better understood by comparing contemporaries in each side. Trump is exponentially worse for workers than Biden, as Biden is doing things such as working with unions and cancelling some student debt.
This still doesn't answer the question. You said "we [communists] agree with liberals more than fascists". Why do we agree more with Biden than Trump? Just because Biden 'works with unions' and 'cancels some student debt'?
Do you think that those workers' lives aren't better because of him? Do you think Trump would do that. Do you think Trump wouldn't try to impede socialist progress more than trump?
