Consumer spending resilience is not broad-based. It's largely driven by the top 10% of income earners (making over $275k), who now account for almost 50% of total spending. This is the only cohort whose spending has outpaced inflation since the pandemic, making the wider economy highly sensitive to their behavior.

The resilience of consumer spending, despite weak employment growth, is driven by affluent consumers liquidating assets or drawing down cash. This balance sheet-driven consumption explains why traditional income-based models (like savings rates) are failing to predict a slowdown.
While high-income spending remains stable, the next wave of consumption growth will stem from a recovery in the middle-income segment. This rebound will be driven by stabilizing factors like reduced policy uncertainty and neutral monetary policy, not a major labor market acceleration.
The AI boom's economic impact extends beyond direct investment. With AI plays driving 80% of stock market gains, a powerful 'wealth effect' is created. This disproportionately benefits the top 10% of earners, who in turn drive the majority of US consumer spending, fueling the broader economy.
Despite a still-growing labor market, real wage growth has slowed to "stall speed." This lagged effect on middle and lower-income households is the primary driver for the projected 2-percentage-point drop in real consumption growth for Q4 and Q1.
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 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 economy is now driven by high-income earners whose spending fluctuates with the stock market. Unlike historical recessions, a significant market downturn is now a prerequisite for a broader economic recession, as equities must fall to curtail spending from this key demographic.
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.
The economy's apparent strength is misleadingly concentrated. Growth hinges on AI-related capital expenditures and spending by the top 20% of households. This narrow base makes the economy fragile and vulnerable to a single shock in these specific areas, as there is little diversity to absorb a downturn.
