I think the main point of the song is the oft-repeated line: "Hold on to people, they're slipping away." He's saying that, through everything, what we most need in the world is to keep connecting to others. It can be hard, in a world so full of hate--because you have to live defensively, almost. He's saying that we have to hold onto what humanity is left in the world, hold on to others. He's talking about the fractured way we live our lives, the disconnected pieces of the world working towards different goals every day.

Most of all, this song is about unity, I think.
