The disconnect between strong GDP data and public dissatisfaction (the 'vibe-cession') is because wealth gains are concentrated at the top while median outcomes worsen. This K-shaped dynamic is politically unsustainable, forcing politicians away from supply-side policies and toward more populist, and often inflationary, measures.

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.

Aggregate economic data looks positive because the top 10% of households drive consumption. However, the bottom 90% are experiencing financial distress, which is reflected in negative consumer sentiment. The 'average' consumer experience doesn't exist, leading to a disconnect between official statistics and public perception.

Despite headline economic growth, the bottom 80% of U.S. households have seen their spending power stagnate since before the pandemic. Their spending has grown at exactly the rate of inflation, meaning their real consumption hasn't increased. This data explains the widespread public dissatisfaction with the economy.

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.

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.

While headline GDP figures seem positive, the US economy shows signs of weakness. Growth is driven by high-income households drawing down savings, while the job market is stagnant outside of the healthcare sector. This creates a "K-shaped" dynamic where macro numbers obscure underlying fragility.

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.
