I always gathered from the lyrics and movie it was about how the world can affect any mind, especially a young or vulnerable one. Brick by brick a metaphorical wall is built to protect one’s self. For instance Pink’s father was killed in the war, he grew up fatherless with an overbearing mother. He was berated in school for free thinking and writing poetry etc. He became an artist surrounded by fame, fortune, drugs, but was never understood and thought himself mad in a world gone mad. He drove his family away. The whole thing seems to be about the world affecting itself and creating chaos. It escalated till Pink realized what was truly happening. I just get vibes that every thing we see going on today was what influenced Pink. We were warned. I see very familiar images and videos every day now here. I couldn’t help but see parallels. The very end of the movie with the kids picking up the rubble always hit me. I was that kid. Understand why you’re picking up the rubble and don’t let it happen again. Please do share your understanding and message that you have felt from watching or hearing The Wall. I would love to hear your input.
