Picture a house, and a room on the upper floor filling with smoke. You can do a great deal about that smoke. You can run a powerful extractor, set air purifiers along the wall, throw the windows wide — and the smoke will thin, and the room will clear. None of this is illusion. It genuinely works.
But if down in the basement the source goes on burning, you will have to keep the extractor running always. Switch it off, and the smoke comes back — not because the extractor failed, but because you were working on the smoke and not on the thing that makes it.
These two storeys do not stand in for one another. The first storey today has everyone talking — a whole industry, bright and crowded and well-attended. The second has almost no one. And it is precisely the second that, in so many people, stays untouched, however much they pour into the first.
Most people live only on the upper floor and never go down into the basement, where it burns. I am suggesting that you go down and look.
