Society.

I changed a few of the lines in the song to personalize it to my experience.
Insanity is a sane reaction to a crazy world.
I urge all people to not stigmatize a brain illness.
Just because mental illnesses are not visible to the naked eye
does not mean that it is non-existent.
I guess to contrast my point, are people with diabetes
marginalized because of weak moral fiber and will-power?
I think the original intent of the tune was to
point out that the United States Jail System is tantamount
to Concentration Camps, leaving enormous numbers of people
absolutely vacant from everyday life.
One last little note,
Eddie Vedder used an old folk trick to compose the song.
John Lennon used the same device in his song, Working Class Hero.
I will get off the stump now.
Thank for bearing with me.
