Debt: The Distinction That Changes Everything

The Old Concepts: All Debt Is Bad, Risk Is to Be Avoided, and Business Is for Other People

Let me tell you what I grew up hearing about debt, risk, and business, because I suspect it sounds familiar.

Debt was something to avoid at all costs. Responsible people did not borrow money unless they absolutely had to — for a house, perhaps, with the understanding that the mortgage should be paid off as quickly as possible. Consumer debt was a moral failing. The ideal was to live within your means, save carefully, and never owe anyone anything. This was not presented as one possible financial strategy. It was presented as the only honorable one.

Risk was similarly framed. The responsible path was the stable path. A regular job, a savings account, and a predictable income. Taking financial risks — investing, starting a business, using leverage — was what reckless people did and then regretted. The cautionary tales were always about risks taken and punished. The stories about risk avoided and its long-term cost were not told, because the cost was invisible and accumulated slowly over decades.

Business was for people with capital. Starting a business required money for premises, staff, inventory, and equipment. The barriers were real and significant. Most people did not have those resources, and the advice they received — get a stable job, do not take unnecessary risks — was reasonable given those constraints. The problem is that those constraints have changed substantially, and the advice has not been updated with them.


All three of these old concepts were formed in response to real conditions that existed in a specific economic era. They are not irrational beliefs. They are beliefs that made sense in a world of limited financial instruments, high business formation costs, and institutional stability that no longer exists at the same level. The question is not whether these beliefs were once reasonable — they were. The question is whether following them now, in different conditions, produces the outcomes they were designed to produce. For a significant proportion of people, it does not.

Debt: The Distinction That Changes Everything


The old concept treats all debt as equivalent. The new concept makes a distinction that fundamentally changes the analysis: there is debt that costs you money, and there is debt that makes you money. Treating them as the same category — avoiding both equally on principle — is like refusing to use any tool because some tools can cause harm if misused.

Destructive debt is straightforward. Credit card debt charging 20 percent annually, consumer loans financing depreciating assets, payday loans at usurious rates — these are forms of debt that cost more than any reasonable investment could return. They extract from your financial position over time. Avoiding them is genuinely wise. The old concept’s caution about this category of debt is correct and worth maintaining.

Productive debt is different. A mortgage at four percent on a property that generates a rental income at a six percent yield is a financial instrument in your favor. The bank is lending you money at four percent to generate a six percent return — the spread is yours. A business loan at six percent, used to acquire equipment or inventory that generates twenty percent returns on the capital deployed, is a multiplier on your productive capacity. The debt does not cost you money in net terms — it makes you money by providing capital to deploy into returns that exceed the cost of borrowing.

The fundamental principle of productive debt — which sophisticated investors have always understood and which the old concept actively obscured — is this: the relevant question is not whether you are borrowing, but whether the return on what you borrow exceeds the cost of borrowing. When it does, debt is a financial tool. When it does not, it is a financial drain. That single distinction, properly understood, changes what a person does with mortgage flexibility, business financing decisions, and investment leverage in ways that the blanket avoidance of debt structurally prevents.

Howard Marks, co-founder of Oaktree Capital Management and one of the most respected investors alive, addressed this directly in a 2024 memo on debt: the amount of leverage that is prudent to use is purely a function of the riskiness and volatility of the assets it is used to purchase. Stable assets with predictable returns — quality rental property, diversified investment portfolios, established business operations — support more leverage than volatile assets where returns are unpredictable. The risk is not in the debt. It is in the mismatch between the volatility of the asset and the inflexibility of the debt obligation. Understanding this distinction is what separates intelligent debt use from the reckless leverage that produces the cautionary tales.


None of this is an argument for borrowing carelessly. High-interest consumer debt remains destructive and should be eliminated before any investment activity is considered. What it is an argument for is replacing categorical debt avoidance with analytical debt evaluation — asking whether the return on the borrowed capital will exceed its cost, rather than treating the question as already answered by the presence of debt itself.
