The balance of consumer power in the United States has tilted sharply toward the top of the income ladder. The vast majority of households now account for their smallest slice of overall spending since the pandemic began, even as affluent Americans keep swiping their cards and booking trips. That shift leaves the economy more exposed to the moods and market fortunes of a relatively small group of wealthy consumers.
How the bottom 80 percent slipped into the background
The most striking change is not that rich households spend a lot, which has always been true, but that the rest of the country has been steadily sidelined. The bottom 80% of American earners once provided the broad base of demand for everything from groceries to used cars, yet their share of total outlays has now fallen to its lowest point since Covid upended daily life. Reporting earlier this month described how the 80% of households who sit below the top tier are now cutting back, trading down to cheaper alternatives and postponing big-ticket purchases that once anchored middle class life.
When I look at how that plays out on the ground, it shows up in choices that feel small but add up fast. Families that might have bought a new 2024 Honda CR‑V are stretching the life of a 2015 model instead, or swapping a week at Disney World for a long weekend at a nearby state park. The same reporting on the Bottom 80% of Americans notes that many American households are delaying major purchases altogether, a pattern that hits sectors like autos, appliances and home improvement especially hard. Those decisions reflect not just caution but constraint, as paychecks fail to keep pace with rent, child care and medical bills that eat into what used to be discretionary cash.
The wealthy step in as the main growth engine
As the broad middle and working class pull back, high earners have effectively become the economy’s main prop. A detailed analysis from Sep, conducted by Moody, found that almost all of the growth in U.S. consumer spending since the pandemic has come from the wealthiest households, a conclusion drawn from a wide review of card transactions and other data. That Moody analysis underscores how dependent overall demand has become on a relatively thin slice of the population whose incomes are tied to stock portfolios, executive bonuses and business profits.
New data released in Sep show the same pattern from another angle, with a small share of wealthy households now carrying much of the nation’s consumer spending and, by extension, much of its growth. One review of the numbers found that a small share of wealthy Americans is doing the heavy lifting to support overall US economic growth, filling in the gap left by more cautious middle income shoppers. I see the evidence in booming luxury hotel bookings, record sales of high‑end EVs like the Mercedes‑Benz EQS, and crowded airport lounges even as discount retailers warn of softer traffic.
The shrinking footprint of everyday Americans
What makes this moment different from past cycles is how sharply the spending footprint of everyday Americans has narrowed. Earlier this fall, fresh figures showed that the top 10% of earners now account for a growing share of U.S. consumer spending, while the rest of the country is stuck in neutral or retreat. In contrast, the bottom 80% have seen their contribution to overall spending slip to the smallest share since the pandemic began, a shift that was highlighted when Some economists warned that such concentration could even influence interest rate decisions by the Federal Reserve.
For retailers and service providers that built their business models around broad based demand, this is a profound change. Big box chains that once relied on steady traffic from middle income Americans now find that growth is coming from premium private label lines and high income shoppers who are less sensitive to price. Meanwhile, the same Bottom 80% of Americans who are trading down and delaying purchases are also more likely to hunt for discounts on apps like Target Circle or Walmart’s Savings Catcher, or to cancel subscriptions to services like Spotify Premium and Netflix when budgets tighten. The result is a consumer landscape where the American majority is still present but less decisive, overshadowed by the spending power of a much smaller, richer group.
Why a top-heavy consumer base is a risk
A consumer economy that leans so heavily on affluent households may look resilient on the surface, but it carries hidden fragilities. When a narrow group of wealthy Americans drives most of the growth, their reactions to market swings, political shocks or global crises can have outsized effects. The same Sep work by Moody that documented the surge in high income spending also warned that the economy is now reliant on the fortunes of the well to do, meaning a bout of stock market volatility or a sudden drop in executive bonuses could quickly translate into weaker demand. In that research, Moody economist Mark Zandi noted that for those in the bottom income tiers, the pandemic era savings cushion has largely been spent down, while the top group still has ample reserves, a contrast captured in his observation that “For those in the bottom part of the distribution, the excess saving is pretty much gone, but that is not the case for those at the top.”
From my vantage point, that imbalance turns what used to be a stabilizing force into a potential amplifier of downturns. When the broad middle class is spending, a pullback by the rich can be cushioned by millions of smaller purchases, from school supplies at Dollar General to family dinners at Applebee’s. Today, with the bottom 80% already stretched and cautious, there is less of a buffer if high earners suddenly decide to skip the kitchen remodel, cancel the Tesla Model X upgrade or postpone a European vacation. The economy may look strong as long as markets are rising and corporate profits are robust, but it is more exposed to a change in sentiment among a relatively small group of households.
What this means for policy and business strategy
The growing gap in spending power is not just a curiosity for economists, it is a practical challenge for policymakers and executives. For the Federal Reserve, a consumer sector powered by wealthy Americans complicates the task of reading the data: headline spending can look healthy even while the majority of households are under strain. That is one reason Some economists have flagged the risk that rate setters might misjudge how much pain higher borrowing costs are inflicting on the bottom 80%, whose smaller share of total spending can mask their stress in aggregate numbers. If the Fed focuses only on robust card swipes from the top 10%, it may keep interest rates higher for longer than middle and lower income Americans can comfortably bear.
Corporate leaders face a similar strategic fork. One path is to chase the money and double down on affluent customers, expanding luxury offerings, premium loyalty tiers and concierge style services that cater to the top 10%. The other is to recognize that long term growth still depends on the financial health of the broader population, and to invest in products and pricing that keep the Bottom 80% of Americans engaged. That could mean more durable mid range appliances instead of only high margin smart models, or flexible payment plans that do not trap American families in revolving debt. As I see it, the smallest spending share in years for the vast majority of Americans is not just a statistic, it is a warning that an economy balanced on a narrow peak of wealth is far less stable than one supported by a wide, confident base.
