There is more to Bannon than simply being an “economic nationalist”.     Consider plans to repeal the Affordable Care Act, reduce oversight of Wall Street, reduce environmental oversight, repeal restrictions that keep religious leaders influencing from the pulpit, reduce restrictions on gun control, reduce reliance on publically funded schools, etc, etc.  

This is an attack on government.  Bannon is either a radical Libertarian or has a massive hate-on for the way government departments currently execute  their responsibilities.   Either way, he plans to dismantle many of the Government departments that protect a safe and secure middle-class.   For a guy who hates elites, he is setting the wheels in motion to create a country that is even more divided between haves and have-nots.   The elites will have most to  gain under his leadership.
