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.

The US innovation ecosystem is fueled by a culture of risk-taking, which is incentivized by a regressive tax system at the highest levels. The tax rate plummets for the wealthiest 1%, creating an enormous potential upside that encourages venture creation, despite the lack of a social safety net.
When government policy protects wealthy individuals and their investments from the consequences of bad decisions, it eliminates the market's self-correcting mechanism. This prevents downward mobility, stagnates the class structure, and creates a sick, caste-like economy that never truly corrects.
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.
Just as NAFTA brought cheap goods but eliminated manufacturing jobs, AI will create immense productivity via a new class of "digital immigrants" (AIs in data centers). This will generate abundance and cheap digital services but risks displacing vast swaths of cognitive labor and concentrating wealth.
Extreme wealth inequality creates a fundamental risk beyond social unrest. When the most powerful citizens extricate themselves from public systems—schools, security, healthcare, transport—they lose empathy and any incentive to invest in the nation's core infrastructure. This decay of shared experience and investment leads to societal fragility.
The top 10% of earners, who drive 50% of consumer spending, can slash discretionary purchases overnight based on stock market fluctuations. This makes the economy more volatile than one supported by the stable, non-discretionary spending of the middle class, creating systemic fragility.
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.
The economic system champions individual responsibility for the middle class but provides government bailouts and shields large corporations and the wealthy from failure. This cronyism prevents creative destruction, calcifies the class structure, and stifles opportunities for new entrants.
As governments print money, asset values rise while wages stagnate, dramatically increasing wealth inequality. This economic divergence is the primary source of the bitterness, anxiety, and societal infighting that manifests as extreme political polarization. The problem is economic at its core.
