Just about every circuit you see drawn show a earth ground symbol, whether it is actually meant to be at earth ground or not, instead of where frame or chassis should be used.
This often leads to alot of confusion.
One book considered the Electronic bible by many, The Art of Electronics by Horoitz and Hill. commit this error all the way through the book.
