The quiet weight of debt

Debt behaves like a light gravity.

It does not knock you over. It rarely looks dramatic. It simply makes every subsequent move a little harder. You can still stand. You can still walk. But when the moment arrives that asks you to jump, you find you cannot jump as high as you once could.

That is debt.

Two different things wearing one word

Debt is sometimes leverage. A sensible home loan, held over a long period, has built a great deal of Australian wealth and there is no honest argument against it.

The debt that does the damage is a different animal wearing the same word: consumer debt, lifestyle debt, and the slow accumulation of obligations that arrive with a certain kind of life. That debt does not give you power. It removes your options, one at a time, so gradually that no single removal is worth objecting to.

In a low-rate year with gentle markets, everyone with a microphone says the same thing. Debt is the tool of the wealthy. Leverage amplifies returns. The people afraid of debt are the same people who never get rich.

In that kind of year the argument is unanswerable.

Then conditions change. Rates rise, markets shake, jobs stop holding the way they used to. And the people who found the argument unanswerable — who took the leverage to its limit because the maths said they could — begin to discover, one by one, that what they had overlooked was never the maths.

It was the structure.

The uneven bargain

The structure is this. Your income can disappear overnight. Your assets can devalue overnight.

Your debts cannot.

That asymmetry is what makes debt dangerous in a way no spreadsheet captures, because a spreadsheet models all three as variables and only two of them actually are. It does not show up in the good years at all. It shows up only in the years that pin you to the floor, which are also, reliably, the years in which opportunities are cheapest.

That is the visible cost. The deeper one never appears on any statement and is far more expensive.

What it actually costs

Consider James, who works in middle management at one of the major banks.

Three years ago a new manager arrived above him with a coercive style. Staff began to crack under sustained pressure. James was instructed, in internal meetings, to characterise those breakdowns as individual psychological problems.

He knew it was wrong. His wife knew. He knew that his subordinates knew that he knew.

And he could not leave.

The mortgage, the car loan, the school fees, the private health cover for his parents — added together, they meant he could not afford to be away from work for a single day.

What makes a position like that corrosive is not that you cannot see it clearly. You see it perfectly clearly. That is the whole problem.

James did not want to stay inside something he had come to think of as toxic. He did not want his own seniority used to underwrite a version of events he knew to be false.

He went anyway, every morning, for three years.

This is not what we lazily call financial pressure. It is something more precise: the slow conversion of a person's convictions into things they can no longer afford to hold.

The number nobody calculates

There is an arithmetic most people never perform.

Not the interest rate. Not the repayment. The question is: how many months could I go without income before something breaks?

If the answer is less than three, you do not have a debt level. You have a constraint on what kind of person you are able to be at work — and that constraint will be tested, eventually, by a manager, a merger, or a request you should refuse.

The people who can say no at work are almost never the bravest people in the building. They are the people whose fixed costs are low enough that the sentence is survivable.

Courage, at that level, is largely a balance-sheet item.

Where the caution stops

None of this argues for holding no debt at all, and the version of this argument that ends in "never borrow" is as unexamined as the version that ends in "leverage everything".

A mortgage taken at a level you could service on one income, on a home you intend to keep, is not a gravity. It is a structure. The distinction is not the presence of debt but whether the debt has a claim on your choices — whether it can, at some future moment, tell you what to say in a meeting.

Ask it directly of each obligation you carry. If this were removed, what would become possible that is not possible now?

For a well-judged mortgage the answer is usually: not much, and I would be paying rent instead.

For the car, the fees, the accumulated conveniences, the answer is sometimes a good deal more uncomfortable — and worth hearing before the year that tests it.
