Another possible and likely problem is if the neutral opens somewhere in the
house it would cause the equipment to not work. For example, you plug your
stereophonic in with an open neutral, it wont turn on. Then while you are
trying to figure out why, you grab hold of your RCA console TV which is also
plugged in, but on a different branch circuit where the neutral is intact.
Now your body becomes the neutral between your stereophonic and the RCAs
neutral.
It may be overkill (bad choice of words?) , but most skydivers wear a backup
parachute , the ground is really that backup chute.

A lot of the residential wiring back then lacked a dedicated grounding
conductor. It only had two wires, a "hot" and a neutral, unlike the wire
used today which has three wires including a dedicated grounding
conductor. The neutral was also used as an equipment safety ground. If
the neutral opened up somewhere in the circuit, such a bad splice
somewhere in the house, you no longer had a ground and ugly things
happened when shorts would develop between the 120V conductor and the
cabinet.
