This song recopilates a lot of hidden meanings, but mostly in the song we can recognize that it is talked about of how the governments manipulate people, and try to silence and end with the free expression "hypnotizing them into believing what they say. This keeps people from standing up to their governments."
So, going on with this meaning, we have an example used at the song:Tiennamen Square. When the students stood up to the government and protested, the government sent the army to kill these people.

Lyrics:
Why don't you ask the kids at Tiananmen square?
Was Fashion the reason why they were there?
They disguise it, Hypnotize it
Television made you buy it
I'm just sitting in my car and waiting for my...
She's scared that I will take her away from there
Her dreams that her country left with no one there
Mezmerize the simple minded
Propaganda leaves us blinded
I'm just sitting in my car and waiting for my girl
I'm just sitting in my car and waiting for my girl
I'm just sitting in my car and waiting for my girl
I'm just sitting in my car and waiting for my
Girl
Was Fashion the reason why they were there?
They disguise it, Hypnotize it
Television made you buy it
I'm just sitting in my car and waiting for my...
She's scared that I will take her away from there
Her dreams that her country left with no one there
Mezmerize the simple minded
Propaganda leaves us blinded
I'm just sitting in my car and waiting for my girl
I'm just sitting in my car and waiting for my girl
I'm just sitting in my car and waiting for my girl
I'm just sitting in my car and waiting for my
Girl
