No, horses and fountain pens do not exist in any real sense today vs. the economic impact they once had. They are niche hobbies that could disappear tomorrow and the economy wouldn't even notice. They used to be bedrocks where the world would stop turning without them overnight if they disappeared. The folks put out of work would be a rounding error on yearly layoffs if every horse and pen was zapped out of existence tonight.

They are incredibly niche side industries largely for the pleasure of wealthy folks. Horses still have a tiny niche industrial use.
