Recent job growth is overwhelmingly concentrated in healthcare services (83% of new NFP jobs) for an aging population. This, combined with an AI capex bubble, reveals a non-dynamic, 'K-shaped' economy where 'Main Street' stagnates and growth depends on narrow, unsustainable drivers.

Today's market is more fragile than during the dot-com bubble because value is even more concentrated in a few tech giants. Ten companies now represent 40% of the S&P 500. This hyper-concentration means the failure of a single company or trend (like AI) doesn't just impact a sector; it threatens the entire global economy, removing all robustness from the system.

The US economy is not broadly strong; its perceived strength is almost entirely driven by a massive, concentrated bet on AI. This singular focus props up markets and growth metrics, but it conceals widespread weakness in other sectors, creating a high-stakes, fragile economic situation.

The global economy's dependence on AI has created a massive concentration of risk in NVIDIA. Its valuation, exceeding the entire German stock market, makes it a single point of failure. A significant drop in its stock—which could still leave it overvalued—would have catastrophic ripple effects with nowhere for capital to hide.

The U.S. economy can no longer be analyzed as a single entity. It has split into two distinct economies: one for the thriving top tier (e.g., AI and tech) and another for the struggling bottom 60%. The entire system now depends on spending from the rich; if they stop, the economy collapses.

Large-cap tech earnings are hitting record highs, driving stock indices up. Simultaneously, core economic indicators for small businesses and high-yield borrowers show they have been in a recession-like state for over a year, creating a stark divergence.

The global economy's reliance on a few dominant tech companies creates systemic risk. Unlike a robust, diversified economy, a downturn in a single key player like NVIDIA could trigger a disproportionately severe global recession, described as 'stage four walking pneumonia.' This concentration makes the entire system fragile.

The top 10% of US earners now drive nearly half of all consumer spending. This concentration suggests the macro-economy and stock market can remain strong even if AI causes significant unemployment for the other 90%, challenging the assumption that widespread job loss would automatically trigger an economic collapse.

With the top 10% of earners accounting for half of all consumer spending, the U.S. economy has become dangerously top-heavy. This concentration creates systemic risk, as a stock market downturn or even a minor shift toward caution among this small group could trigger a sharp recession, with no offsetting demand from the rest of the population.
