🫁 Let Money Breathe

Markets and finance are among humanity's greatest inventions. They have lifted billions from poverty, funded innovation, and transformed ideas into industries. We should strengthen them — not weaken them. My concern lies elsewhere.

The World Has Changed Faster Than Our Thinking About It

Traditional economics gave us invaluable foundations, and I have great respect for the economists whose work shaped generations of students, including myself. Their ideas remain essential. But no textbook should become the final chapter of economic thought.

Today's economy moves at extraordinary speed. Companies have grown from millions to billions, and now to trillions in value within a single generation. Artificial intelligence, robotics, digital networks, and global connectivity are reshaping production, work, and wealth in ways previous generations could scarcely imagine. Our theories must evolve with this reality.

The pace is not a figure of speech. Apple needed just over eight years to travel from its first trillion, in August 2018, to its fifth, reached today. Nvidia made the identical journey — $1 trillion to $5 trillion — in roughly two and a half years, becoming along the way the fastest company in history to double from $1 trillion to $2 trillion. Only about ten companies have ever crossed the trillion-dollar line at all, and it took markets over a century to produce the first one. The gap between Apple's eight years and Nvidia's two and a half is not a rounding error. It is a measure of how much faster capital now compounds at the very top of the economy than it did even one business cycle ago.

Money Is a Flow, Not Just a Store — and the Data Agrees

Every living system thrives through movement. Economies are no different. Money is not merely a store of value; it is also a flow of value. When capital circulates, it creates businesses, jobs, innovation, and opportunity. When it becomes excessively concentrated or stagnant, economies lose dynamism.

This is not a metaphor waiting to be proven. The Federal Reserve tracks it directly, as the velocity of M2 money stock — literally, how many times a dollar changes hands in productive transactions over a given period. From the late 1950s through the mid-1990s, that velocity held in a range of roughly 1.65 to 1.9. It peaked at 2.192 in the third quarter of 1997, at the height of the dot-com boom, when money was changing hands fastest. Since then it has been in near-continuous decline: down through the 2008 financial crisis, down further as quantitative easing expanded the money supply without a matching expansion in how often that money actually moved, and down to an all-time low of 1.126 in the second quarter of 2020. As of early 2026, velocity sits at 1.409 — a real recovery from the 2020 floor, but still roughly a quarter below where it sat for almost the entire second half of the twentieth century.

Read the two data points together and the picture sharpens considerably. Capital compounding at the top is accelerating — Nvidia's run is the clearest single data point, but the broader pattern of capital pooling into an ever-smaller set of winners is one this letterhead has already documented at length. Capital circulating through the rest of the economy has not kept pace; by the Fed's own measure, it still moves distinctly slower than it did for most of the postwar era. Both things are true in the same economy, at the same time.

This Is Not an Argument Against Wealth

This is not an argument against wealth or successful investors. Capital is essential. But capital reaches its highest purpose when it helps create broader prosperity rather than remaining idle. Money, like fresh air, is most valuable when it moves.

That is why I write what I call "hidden gems" — ideas that question established assumptions while respecting the achievements of the past. The goal is not to discard classical economics, but to extend it for an age of intelligent machines, global networks, and unprecedented technological progress. The future will not be built by choosing between old economics and new economics. It will be built by combining the wisdom of the past with the courage to imagine what comes next.

Why This Belongs in NGE's Founding Framework

This letter is less a single thesis than a statement of the standard the rest of this letterhead tries to hold itself to. When capital flows toward innovation, opportunity, and human potential, markets become stronger, societies become more resilient, and humanity flourishes. That is the economics worth building — and it is the reason every letter published here, from the Hidden Capital series to Economic Gravity, keeps returning to the same underlying question: not whether capital is good or bad, but whether it is moving.
