Feds as in the entirety of federal government and its instruments. Also i didn’t said it won’t ever happen, but as you can see they have been incredibly successfull up to date in fighting specifically socialists. I would rather say what will get rid of the government won’t be a socialist revolution (that will come later after probable period of turmoil). Most likely they will at some point implode under its own weight much like most empires in history, especially that there won’t be any outside military intervention which usually speed things up.
