Lyric discussion by Griffinfuhrer 

Incredible song. Here's what the lyrics mean;

The "21st Century Shizoid Man" is a person of the near future. Pretty much paints an unflattering portrait of the future-- as we see on television and such the future is going to be a place where dreams will come true, King Crimson decides to be less optimistic and more realistic.

"Cats Foot Iron Claw"

Means that all that is organic will be replaced with machines.

"Neuro-surgeons scream for more"

The future is going to be a crowded stressful mess, people will be worked to the bone and insanity will be rife. Thus the neuro-surgeons will capitalise on the madness that will ensue

Second verse, the future is going to be a place of much suffering and war

"Poets starving children bleed"

Art will be shunned upon in the face of commercial superficiality. The people who try to get their messages across-- ie "the children", will be ignored in the face of conformist pop culture

"Nothing he's got he really needs"

Electricity, television, movies, etc, all of these things that are slowly consuming our resources in the name of keeping people happy.. things like that that greedy people of the future will consume and operate by the truckload.. we really don't need them

I think your interpretation was really interesting and quite good.

However, I think, give the year this was written, it's much more about the Vietnam war.

Being only 20 and not living at the time of the war, I can't decipher all of the symbols and some of what I do decipher may be wrong, but here's my take on it.

I disagree that the song is not about greed. The first verse brings that concept in with neuro-surgeons screaming for more. It is their greed that feeds the paranoia. It is so prophetic too because here we are in the 21st century and pharmacutical companies control us. Psycho bablers work hand in hand. It is huge money. I also don't think the least useful line is "nothing hes got he really needs." In fact, I think that is one of the better lines. The line that makes this song out of date is the reference to napalm. For you Britts...

@Griffinfuhrer isn't cat's foot another way of saying cat's paw?
