The question
Is the economy really K-shaped?
At the pump: two Americas, one gallon.
A gallon of regular costs the top tenth of earners 3.5 minutes of work right now. The bottom tenth pays 15.7 minutes for the same gallon: a gap of 12.3 minutes, wider than 56% of the quarters since 2000. The widest it has ever been was 2008 Q3, at 21.4 minutes.
What a K-shaped economy is
An economy where the arms move apart. Spending and wealth climb at the top; the bottom half stalls, or slips. The term took over the argument about how the economy is doing (one side points at asset prices, the other at groceries and rent), and most of that argument runs on vibes plus one quarter of data. The pump keeps longer books: every week since 1990, every month since 1980, priced against what workers actually earn.
The average worker is two different people
Our work lens divides the pump price by the average hourly wage. This chart stops averaging. Split the same gallon across the wage scale and the single line opens into a fan: cheap gas at the top of it, expensive gas at the bottom, and the minimum-wage line above them all.
Read the bottom two lines together and the chart argues with its own headline. The gap is real (15.7 minutes against 3.5), but the bottom’s worst stretch was 2008 Q3, not now. And through 2021–23 the lowest-paid workers had the fastest wage growth in the data, which pulled the bottom of the fan closer to the median than it stood in the 2010s. The K didn’t arrive with the headlines. It has been here the whole time, opening and closing.
The gap, isolated
Subtract the top line from the bottom and the K collapses to one number: how many extra minutes the bottom-tenth worker spends earning the same gallon. The shape is a mountain range, not a staircase.
The peaks are price spikes. 7.4 minutes in early 2002; 21.4 in the summer of 2008, when $4 gas landed on the widest wage spread in the series; about 11 through 2019, and 12.3 now. The arithmetic is blunt. The gap is the wage spread times the pump price, so a spike multiplies whatever inequality is already there. Congress and employers move one factor; the oil market moves the other, faster.
The minimum-wage gallon
The federal minimum wage has been $7.25 since July 2009, the longest freeze since the wage was invented. The gallon kept moving anyway. Most low-wage workers now earn above it because their states set higher floors, so this line is a boundary, not a typical worker. But the boundary is the point: it is the one wage Congress prices, and it has bought less gas almost every year since 2009.
Here is that boundary as its own chart, with every hike marked on the axis.
Every step down is a law. Every climb is the pump moving against a wage that stands still. The record, 41.6 minutes in June 2008, came one month before the second of the 2007–09 hikes cut it back. Nothing has cut it back since.
The clearest K is in the budget
Minutes per gallon understates the split, because the two arms don’t buy the same number of gallons relative to what they make. In 2024, the bottom fifth of households put 7.58% of their pre-tax income into gasoline; the top fifth, 1.49%. Same commute, 5.1 times the bite. When gas spikes, the top quintile rounds it away. The bottom quintile rearranges the month.

What the pump can’t see
This page rules on fuel and paychecks, because that is the data we keep. The K-shaped argument is bigger: who owns stocks and homes, and whose credit cards are slipping into delinquency. On those, read the New York Fed’s breakdown and PBS’s reporting. A pump’s-eye verdict is narrow on purpose; we would rather be right about a gallon than vague about everything.
The Treasury Secretary says it’s over
On August 12, 2026, Treasury Secretary Scott Bessent said the K-shaped economy “is over.” That is a checkable claim, so we wrote it down. Our gauge is the ratio of the median wage to the 10th-percentile wage: if the K is over, the bottom should be closing on the middle and staying there.
Drawn out, the gauge tells its own story. The bottom lost ground to the median for a decade, peaking at 2.14× in 2012 Q2, and has been clawing back since the mid-2010s. The dashed line is the bet.
As of 2026 Q2, the ratio is 1.95, already below its 2015–19 average of 2.07: the 2021–23 wage compression at the bottom has held so far. So on this gauge he is not wrong today. The bet is whether it lasts: if the ratio is still below that baseline at the end of 2027, we will say so, on this page. If it has reopened, that too. This is standing bet #5 on the list of things that would change our mind.
