The Gap Isn't Income. It's Whether You Already Own Something.

TL;DR

Sort American families by income and you get one picture. Sort them by whether they own their home and you get a different one. In 2022 the median homeowner’s family income was $94,000 against renters’ $42,300 — a gap of 2.2 times. Median net worth was $396,200 against $10,400 — a gap of 38 times.¹ The mechanism is visible in the same survey: the median home was worth over 4.6 times median family income, the highest ratio on record, up from 3.5 in 2016.¹ The Federal Reserve states both halves plainly — rising house values are “a boon to homeowners” and “declining housing affordability for would-be homebuyers.”¹ Canada faces the identical arithmetic and answered it with leverage: $1.80 of credit-market debt per dollar of disposable income, a saving rate of 3.5%, and a top wealth quintile holding 65.7% of all household net worth while the bottom 40% hold 3.0%.² Meanwhile Canadian output per hour has fallen from 88% of the US level in 1984 to 71% in 2022, which its own central bank called an emergency.³ Same trap, two exits, neither of them good.

Two Ladders, Not One

Most arguments about whether a country is a good place to build a life get conducted in the currency of income. Salaries, taxes, take-home pay, cost of living. It is the natural currency because it is the one people experience monthly.

It is also the wrong one, and the reason is structural rather than moral.

There are two ladders. One is income: what your labour earns per unit of time. The other is assets: what you own that appreciates without you. For most of the postwar period the first reliably delivered the second — a normal wage, saved normally, bought a normal house on a normal timeline, after which the second ladder took over and did the compounding for you.

What matters is not the height of either ladder but the ratio between them. And that ratio is a price: how many years of income does the entry ticket to the asset ladder cost? When it rises, everyone already on the second ladder gains, everyone still on the first pays more to board, and the distance between the two groups widens with no change in anybody’s effort, talent or wage.

That is a measurable quantity, and it has been measured.

The Cleanest Number in the Data

The Federal Reserve’s Survey of Consumer Finances is the best household-balance-sheet data in the world, and it reports both income and net worth for the same families, cut the same ways. So you can put the two ladders side by side.

Take that in for a moment. Between homeowners and renters, a 2.2-fold income difference sits alongside a 38-fold wealth difference.¹ Whatever is producing the second number, it is not mostly the first. Income differences of that size, compounded over a working life, do not get you to a factor of thirty-eight.

The same skew shows up inside the stock market. Among families who hold any shares at all, directly or indirectly, the median holding in 2022 was $12,600 for the bottom half of the income distribution, $53,200 for the next forty percent, and $608,000 for the top decile.¹ Even conditional on participating, the position sizes are on different scales.

Income tells you what you can spend. It is a surprisingly weak predictor of what you own.

Why the Ratio Moved

Now the mechanism, and it is not subtle.

Between 2019 and 2022 the median net housing value held by American homeowners rose 44% in real terms, from about $139,100 to $200,000 — the largest three-year increase in the survey’s history.¹ Over the same period the price of the median home reached more than 4.6 times median family income, surpassing the 2007 peak of 4.2.¹

Those two sentences describe one event from two sides. For everyone who already owned, a large tax-advantaged transfer arrived unbidden. For everyone who didn’t, the entry price went up by the same amount. The Fed’s report says so directly, in a single sentence that ought to be quoted more often than it is: rising house values “can be a boon to homeowners,” and the same trend “represents declining housing affordability for would-be homebuyers.”¹

No policy did this on purpose. Nobody’s wage was cut. The distance between the two ladders simply grew.

Canada Took the Other Route

Canada has the same arithmetic and a different response to it. Instead of the gap opening between owners and non-owners, Canadian households borrowed to stay on the owning side of it.

The numbers are startling by any international standard. In the first quarter of 2026 the ratio of household credit-market debt to disposable income reached 179.6% — roughly $1.80 of debt for every dollar of income — rising for a sixth consecutive quarter.² The stock of household credit-market debt is $3,253.4 billion. The debt service ratio is 14.75%, meaning close to fifteen cents in every dollar of disposable income goes to principal and interest. And the household saving rate has fallen to 3.5%, its lowest since early 2024, because spending grew faster than income.²

Set those four figures next to each other and the strategy is legible. Households are converting future income into present ownership at a high price, and there is very little margin left over.

Meanwhile the distribution looks like this.

Canada’s wealthiest 20% of households held 65.7% of the country’s total household net worth at the end of 2025, averaging $3.5 million each. Statistics Canada puts the gap between that group and the bottom 40% at 62.7 percentage points — which leaves the bottom two quintiles holding about 3% of the total. The gap widened by 0.6 percentage points over the year.²

There is also a quiet arithmetic point in the same release. Household debt equals just 17.4% of household net worth, which sounds reassuring until you notice that the net worth and the debt are not held by the same households.² Aggregate ratios describe an average family that does not exist.

And the Income Side Is Weakening

The leverage strategy has an unstated assumption: that income will grow into the debt. This is where Canada has a specific problem, and it was named unusually bluntly by its own central bank.

In March 2024 the Bank of Canada’s Senior Deputy Governor gave a speech that opened with an emergency metaphor — “You’ve seen those signs that say, ‘In emergency, break glass.’ Well, it’s time to break the glass” — and then produced the number behind it.³ In 1984 the Canadian economy produced 88% of the value generated by the US economy per hour worked. By 2022 it produced 71%.³

The causes she identified are all supply-side: weak business investment over roughly the past decade, declining domestic competition, and skilled immigrants working in jobs that don’t use the skills they arrived with.³ The transmission to wages is the ordinary one — better tools and training let workers produce more, which lets employers absorb higher wages without raising prices.³

Read that against the debt figures and the bind is clear. A household carrying $1.80 of debt per dollar of income is making a bet on future earnings in an economy whose capacity to generate future earnings per hour has been slipping relative to its neighbour for four decades. The US has its own version of the problem, but not this one: American productivity has accelerated since 2023 to roughly 2.7% a year. Canada’s business-sector productivity was, at the time of the speech, about where it had been seven years earlier.

The Mirror-Image Failure

So the two countries fail at the same thing in opposite ways, and it is worth stating the trade honestly rather than picking a winner.

The US has a higher ceiling and stickier extremes. More upside, thinner safety net, and mobility that is worse specifically at the ends. Miles Corak’s comparison is the standard reference: the American intergenerational earnings elasticity is about 0.5, roughly twice Canada’s, meaning about half of a father’s economic advantage or disadvantage passes to his son, against under a fifth in Denmark, Norway and Finland.⁵ But — and this is the part usually dropped — the middle is mobile in both countries. Decile transition matrices show “a good deal of mobility in both,” to the point of little relationship between family background and child outcomes across broad swaths of the middle. The countries diverge at the edges: more than half of sons raised by top-decile American fathers fall no further than the 8th decile, and about half of those raised by bottom-decile fathers rise no further than the third.⁵

Canada has a compressed ceiling and more leverage. Better mobility at the extremes, lower productivity, and households that have borrowed heavily against an asset class whose price is the main thing standing between them and the ownership they are borrowing to reach.

Neither is the “safe” choice. One asks you to accept more variance; the other asks you to accept more debt and a slower-growing income to service it. Both are versions of the same underlying condition: the asset ladder is pulling away from the income ladder, and the country only determines which failure mode you experience.

This is the material version of a pattern this site keeps finding. The same exam is not the same chance when preparation is purchasable; the same salary is not the same salary when the asset it is meant to buy has repriced. In both cases the rule is uniform, the outcome is not, and the difference lives in the stock of what you already had.

Where I’d Hold This Loosely

Five limits, and the first two cut hard against my own framing.

The 2019–22 American data is a good-news story, and I should not bury it. Real median net worth rose 37% — the largest three-year increase in the modern survey’s history, more than double the next largest — and the increases were near-universal across demographic and economic groups.¹ Every measure of financial fragility in the survey improved: aggregate debt-to-income fell from 101.2 to 89.4, the aggregate leverage ratio from 12.6 to 10.7, and the share of debtors with payments above 40% of income to 6.5%, the lowest on record.¹ Whatever is happening, “everyone is getting poorer” is not it.

And renters’ net worth grew faster in percentage terms than owners’ — 43% against 34%.¹ From $7,300 to $10,400, which is why the ratio still reads 38 to 1, but the direction is the opposite of the one my argument wants. A story about a widening gap has to survive a period in which the gap narrowed slightly in relative terms, and mine only survives because the absolute distance is so large.

Third, ownership is not randomly assigned, so the owner-renter comparison is not a clean natural experiment. Older, higher-earning, more stable households are likelier to own, and some of the 38-fold gap is those characteristics rather than the effect of owning. Age alone does a lot of work here. The comparison shows where the wealth is; it does not by itself prove that buying causes it.

Fourth, the Canadian and American figures come from different instruments — a quarterly national balance sheet built from aggregate accounts, and a triennial household survey — and the reference years differ. I have deliberately avoided constructing a single cross-country ratio out of them, because the definitions of debt, income and household do not line up well enough to bear it. Each country’s numbers are internally comparable; across the border, treat them as two portraits rather than one scale.

Fifth, Corak’s elasticities are a generation old by construction — sons born in the early-to-mid 1960s, measured in the late 1990s — and Corak himself warns that the statistic “does not mean that it measures ‘equality of opportunity’ or the even-more-elusive ‘American Dream.’”⁵ I have used it as what it is: a summary of how much inequality transmits across two generations, in a cohort whose housing market looked nothing like the current one.
