The only real economic populist thing I know Biden did was appoint Lina Kahn as the FTC chair.
Half a trillion dollars spent addressing climate change, huge boosts to domestic manufacturing and unions, resulting in big wage gains for the working class outpacing even historic levels of inflation, income inequality actually going down which usually doesn’t happen in the US, big hike in corporate tax by two trillion dollars to pay for all of that
The fact that Biden wasn’t seen as a victory for working people and progressive goals in the US is a sign of how INSANELY counterfactual our media created political reality is
