1) Thirty years an industrial and commercial electrician and I've never worn
rubber insulated boots, or even known anyone that owned a pair. Gloves,
leather over rubber, for working on large hot connections, but never boots.
Actually, in areas that didn't require steel-toed shoes I wore slip-on boat
shoes.

2) Sorry, but the electrical power companies don't use the earth as a
conductor. Never have. They don't even have a neutral conductor. Power is
distributed using a three phase system invented by Tesla with no specific
reference to the earth. The first public power generator, at Niagara Falls,
was a three phase system. Neutrals are created at the customers transformer
and are usually grounded for safety. There is no current through a ground
wire under normal (non-fault) conditions.

3) Edison championed a DC power distribution system using positive and
negative wires. He didn't use an earth return either.

4) You're right, if an electrical system doesn't have an 'earth safety
neutral' you could walk around with a hot wire in your mouth. However, if
any other piece of equipment developed a fault to ground your teeth would
light up and your tongue would smoke. The ground wire protects you by
tripping a circuit breaker when that first fault occurs. Without the safety
ground, the fault wouldn't trip the breaker and you would be dead.

5) Your ranting and raving would sound a lot more intelligent if it was
based on facts instead of popular misconceptions.
