Spirit's troubles highlight a broader market trend where budget-conscious consumers cut back while the wealthy splurge on luxury. This pattern, once confined to goods, is now evident in services like travel, signaling a potential risk for other budget-focused businesses and an opportunity for luxury brands.

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 success of premium grocer Meadow Lane, selling $17 nuggets while the city mayor pushes for affordable stores, illustrates a K-shaped economy. One consumer segment drives demand for premium brands, while another faces increasing price pressures.

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 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.

Analysis reveals a heavy concentration of spending at the top: the highest decile of income earners is now responsible for 49.2% of all personal outlays. This makes the overall US economy highly dependent on the financial health and confidence of a very small, affluent segment of the population, increasing systemic risk.
