> about barely growing global disposable income.
Perhaps in the developed world, but with china and now southeast asia, india, africa, etc developing, I don't see how global disposable income is barely growing. If anything, there will be hundreds of millions ( perhaps billions ) of people with substantially growing disposable income in the next few decades.

That's one possibility. The other is to grow consumption/demand to meet the supply.
> We have sort of peaked in how much people's Attention can be milked.
Nowhere close to it.
