What do you think this song really means (Signs - Tesla)?

Question

And the sign says Long-haired freaky people need not
apply
So I put my hair up under my hat and I went in to ask him
why
He said you look like a fine outstanding young man, I think
youll do
So I took off my hat, I said Imagine that, huh, me working
for you

Chorus:
Signs, signs, everywhere theres signs
****** up the scenery, breakin my mind
Do this, dont do that, cant you read the sign

And the sign says Anybody caught trespassing will be shot on
sight
So I jumped the fence and I yelled at the house
Hey! What gives you the right!
To put up a fence and keep me out, or to keep Mother Nature
in
If God was here, hed tell it to your face, man, youre some
kind of
sinner

Oh, say now mister, cant you read
You got to have a shirt and tie to get a seat
You cant watch, no you cant eat, you aint supposed to be
here

And the sign says You got to have a membership card to get
inside -
uh!

And the sign says Everybody welcome, come in, kneel down and
pray

Answer 1
