I don’t know. When I actually observe what people on the left say, they offer a path and don’t just rail against the right. It just doesn’t make headlines.
And you can say that means they need to do better at controlling the narrative, but I think the problem is that negative stuff has an inherent advantage when it comes to making headlines. So when the right does their outrageous negative shit: automatic headlines. When the left offers hope and reason: crickets.
Doesn’t mean the left can shrug their shoulders and not strive for better, but they are at an inherent disadvantage because of the nature of our society. (And if you want to say this is largely the fault of capitalism out of control then you’d get no argument from me.)
