Legacy: Why

What Are You Actually Building Wealth For?

Net worth is an output. Whether a family’s wealth lasts is decided by the inputs.

I spend most of my working life looking at wealth: how it is built, how it is structured, how it is protected. For a long time I thought about passing wealth on the way the financial industry does. You accumulate assets, arrange them efficiently, and eventually transfer them with as little as possible lost to taxes and probate.

That is a reasonable way to think about money. It is a poor way to think about legacy.

High income is not wealth, and wealth is not the point

On podcasts I often argue that high income is not wealth. A large salary can disappear into a lifestyle built to match it, and plenty of high earners own very little.

That argument has a second half, and it matters more. Once you start building real assets, the next question is: for what?

Most people answer with a number. A net worth target, a retirement figure, an amount to leave the kids. That is the least useful place to start.

Net worth is an output

In Why I Read the Return Last I wrote that a projected return is not a fact about a deal. It is an output, the thing that falls out of the bottom of a spreadsheet after the assumptions go in at the top.

A family’s net worth works the same way. What produced it, and what decides whether it survives, sits upstream: how the family communicates, what the next generation is actually capable of, and whether anyone agrees on what the money is for.

One frequently cited study by Roy Williams and Vic Preisser looked at 3,250 affluent families and reported that roughly 70 percent of wealth transitions were unsuccessful. Their definition of success was broader than preserving dollars: it included keeping control of family assets and keeping family harmony. They attributed most failures not to taxes or investment performance, but to breakdowns in trust and communication and to heirs who were not prepared for the responsibility.

The exact percentages have since been challenged, and I would not treat 70 percent as a law of nature. The underlying pattern is more durable than the number: when transitions fail, they tend to fail on people, not paperwork.

The part wealth planning concentrates on most may not be the part that determines whether the transition succeeds.

Paper and people

Estate planning and legacy planning are different jobs.

Estate planning is about structure: wills, trusts, titling, taxes, avoiding probate. It is necessary and technical, and it belongs with good professionals.

Legacy planning is about meaning: what the family stands for, how the next generation is prepared, and what the money is supposed to do. Nobody can do that part for you.

An estate plan transfers assets. Only people transfer values. Most families put nearly all of their planning effort into the first and assume the second will take care of itself.

What a legacy is made of

When I list what I actually want to pass on, financial assets turn out to be one item of five:

Financial capital comes last, not because it matters least, but because its job is to serve the other four. For me the purpose of money is freedom of choice: deciding how to spend your time, who to spend it with, and what to work on. Assets accumulated for their own sake can buy comfort. Assets put in service of the other four can buy freedom.

The first four cannot simply be transferred on a balance sheet or delivered by a trust. They have to be developed, and most of that development happens by example.

Comfort or capability

The question I keep coming back to is simple: am I giving my children comfort, or capability?

Comfort is easy to transfer. Capability is not. It comes from struggle, from decisions with real consequences, from being trusted with responsibility a little before you feel ready. Remove every obstacle and you transfer comfort. Money is most useful when it amplifies capability already being developed. It becomes dangerous when it substitutes for it.

Leave your family the tools, not just the toolshed.

That does not mean withholding help. It means matching the challenge to the person: easy enough to succeed at, hard enough that succeeding means something.

Timing matters

Bill Perkins makes a point in Die with Zero that stayed with me. Inheritances often arrive around the time the recipient is sixty, long after the years when the same money might have changed the trajectory of a life. He argues for giving earlier, while it can still matter, and for spending on experiences that keep paying what he calls memory dividends.

You do not have to accept all of his conclusions to take the point: much of a legacy is transferred while you are alive, in time together and in the example of how you actually live.

The question

So here is the question I would put to anyone building wealth, myself included: what are you actually building it for?

If the answer is a number, you have described an output. The inputs are the harder and more important work: the family you are raising, what they know, how they treat each other, and what they believe the money is for.

Net worth is the easiest part of a legacy to measure. It is rarely the part that decides whether the rest survives.
