American Economic Growth Relies on the Wealthy

This disparity between income brackets explains why aggregate spending remains resilient even as hiring slows and consumer confidence wanes. Wealthier demographics continue to drive activity, supported by robust stock market performance and recent tax relief. Conversely, the bottom 10 percent of earners contribute only 4 percent to consumption, highlighting a reliance on high-income households to sustain national growth.

BofA analysts caution that this concentration of demand creates systemic risk. Should equity markets undergo a correction or geopolitical events disrupt high-income spending, the economy would lack a secondary engine to maintain its trajectory. The Federal Reserve now faces the challenge of managing interest rates to balance overall demand against persistent labor market weaknesses. While long-term stability remains the base case, the report suggests that true sustainability requires broadening the recovery to include lower-income consumers, though fiscal constraints may limit the government's ability to bridge this widening divide.
