High earners continue to drive spending as the K-shaped economy remains "firmly intact," according to Moody's Analytics chief economist Mark Zandi. Americans in the top 20 percent by income — those earning more than $175,000 a year — account for nearly 60 percent of outlays, an "astounding" share, Zandi wrote online, citing updated estimates for the first quarter of 2026.
Personal outlays include consumer spending, interest payments on installment debt like car loans and transfers such as donations. The concept of a K-shaped economy, referencing the letter's diverging arms, has become a popular framework for describing uneven economic outcomes, with higher-income Americans pulling ahead while others struggle to keep up. This pattern helps explain why broad measures of the economy do not always reflect the financial struggles many Americans report feeling.
What the Left Is Saying
Progressive economists and Democratic policymakers have pointed to Moody's findings as evidence that traditional economic metrics obscure growing hardship among middle- and lower-income households. Senator Elizabeth Warren (D-Mass.) has long argued that aggregate GDP figures fail to capture how prosperity is distributed, stating that "the economy is working great if you own stock, but it's a different story if you're trying to afford groceries."
Progressive advocacy groups have used Zandi's analysis to push for policies such as an expanded child tax credit, minimum wage increases and stronger worker bargaining power. The Economic Policy Institute, a left-leaning think tank, has argued that labor market policies should prioritize wage growth for the bottom half of earners rather than relying on stock market gains to drive consumer spending.
Some Democrats have also called for restructuring the federal tax code to reduce reliance on capital gains taxation, which disproportionately benefits higher earners and creates what Zandi described as a dependence on "how their stock portfolios are performing."
What the Right Is Saying
Conservative economists and Republican lawmakers have cautioned against overinterpreting spending disparities as evidence of systemic failure. They note that the labor market remains robust with unemployment near historic lows and argue that wage growth for lower-income workers has accelerated in recent quarters.
Senator Thom Tillis (R-N.C.) has argued that "the best antipoverty program is a strong economy," pointing to continued job creation and rising wages at the lower end of the income spectrum. Heritage Foundation analysts have written that consumption-based measures of well-being do not account for improvements in product quality, access to affordable technology or gains in non-monetary living standards.
Some Republican economists have also raised methodological concerns about Zandi's estimates. The American Enterprise Institute has noted that spending data can be distorted by lifecycle effects, as younger households may naturally spend more relative to income while older households save for retirement. They argue this does not necessarily indicate economic distress but rather normal financial behavior across different life stages.
What the Numbers Show
According to Moody's Analytics analysis cited by Zandi: The top 20 percent of earners increased outlays by 6.5 percent over the past year, outpacing inflation. Outlays by those in the bottom 80 percent rose just 2.6 percent, falling short of inflation. In the mid-1990s, high and lower earners accounted for roughly equal shares of consumer spending. Corporate earnings have reflected this divide: Airlines have leaned into premium offerings as higher-income travelers continue to spend while McDonald's executives have cited continued pressure among lower-income consumers.
The share of total outlays by the top 20 percent has grown from approximately 50 percent in the mid-1990s to nearly 60 percent today. Zandi acknowledged that his estimates have faced methodological criticism and may "overstate the case," but maintained the economy remains "K-shaped and becoming increasingly so."
The Bottom Line
The Moody's analysis underscores a persistent tension between headline economic indicators and household-level experiences. With the economy heavily dependent on spending by high earners whose consumption is tied to stock market performance, economists across the political spectrum have raised concerns about vulnerability during market downturns.
What happens next will likely depend on whether wage growth for lower-income workers accelerates enough to broaden consumer spending beyond the top tier of earners. Policymakers in both parties face pressure to address voter concerns about economic fairness while maintaining conditions for overall growth.
