You don't just have to watch out for CPI inflation to be outpaced by productivity. The money supply needs to also outpace productivity if you want the same status quo. I've built up an intuition that the money supply should match changes in productivity, and that if it doesn't it will eventually lead to problems. But it's also notable that the trend is extremely important. If you do match, everything should be fine and this can last forever. If the money supply rises faster than productivity, you see what we've seen these past 50 years since we've been off the gold standard, a huge surge in asset prices. And if productivity rises faster than the money supply, people flee assets and into money. This is called a Deflationary Spiral. But the opposite state is basically an Inflationary Spiral, with people unwilling to spend their assets. Dalio in his "Explaining the Economic Machine" video talks about a "Beautiful Deleveraging". My thought currently is that such a thing isn't possible. If you wait for the debt to get so bad that you have to do something, you can't match productivity anymore. Therefore the only thing you are left to do is grow the money supply less than productivity. And that changes everything. Suddenly the trend is to money. And once the money managers work that out, they all rush out of assets and into cash. This triggers a crash. So it's the trend that dominates, and there is no way to balance the deleveraging.
