The problem is not that Joe Sixpak disbelieves the charts & graphs, it is that he has spending priorities which seem more urgent right now:

If and when a specific Government plan, including who pays and how much, is drawn up, Joe will listen to it (unless somebody has previously closed his mind by calling him a deplorable or a flat-earther.
