>If truly productivity enhancing investment is effectively dead (or, equivalently, there is so much paper wealth chasing a withering set of profitable opportunities for investment), then capital's only game is to chase high valuations backed by future profits, which means playing the Keynesian beauty contest for keeps.

What if profit is dead because wealth is all concentrating in people who don't need it from a marginal consumption standpoint, which means asset prices blow up because everyone rich believes that they need to "invest" that money somewhere... but demand shrivels outside of interestingly-subsidized areas like healthcare because nobody else is making enough to even keep up with the asset price rises?

And without demand, where would innovation come from?

If you accept that the economy can be in disequilibrium, then it is very easy to see how this happens.

Rich people learn a habit that makes them consume less than their investment returns. The difference is reinvested, resulting in a net increase of their equity. Even if you say they spend 90% of their returns on consumption, the last 10% still grow in absolute terms. Since returns are paid proportionally based on the quantity of equity, you can clearly see that money is allocated from where it has high marginal utility to places where it has low marginal utility.

Of course this leads to a contradiction. If money is held by people who have a low marginal utility for consumption, why would investments pay high returns? Your equity is the latent demand that your investments need to pay you the returns in the first place. You'd increasingly be paying yourself. That is equivalent to investing into something that yields a 0% return which in turn is equivalent to doing nothing.

"in people who don't need it from a marginal consumption standpoint".

We need the rich to spend more money. There are plenty of cool ways to do this. Build a mile high pyramid on a Nevadan playa, a canal to the Sea of Cortez to re-flood the Salton Sea, humans on other planets, new city states a la Praxis, interstellar probes, etc.

Some billionaires are doing some of these things. Hope more do in the future.
