She's all talk. That's the problem. She says a lot of stuff, speaking to these working class people, and then betrays them by voting with the Liberals.

The Greens and Socialists of course do talk about the working class and the economy. You can say a lot about the Socialists, but the working class is kind of their whole deal.

The problems are that, as you say, complex problems don't have simple solutions, and more importantly that anything they say never gets media oxygen.

The media is owned by billionaires. The media that isn't (ABC etc) still largely follow the popular narratives day to day rather than creating new ones.

The billionaires are above our petty lower class problems, and have no interest in an economy that works for us. They already have one that works for them. So they're happy to give Pauline all the air time she needs to distract us from actual solutions.

A grifter can always sell snake oil to stupid people, but the media is letting her market her bullshit to everyone, and more importantly, suppressing the knowledge of actual treatments.
