Why Family Wealth Often Disappears by the Third Generation (And What Behavioural Finance Can Teach Us About It)
A behavioural finance perspective on why wealth is often lost across generations—and why passing down money without wisdom may do more harm than good.
Imagine spending 40 years building a successful business.
You work long hours, take calculated risks, invest diligently, pay off your mortgage and gradually accumulate a few million dollars.
Eventually, you leave that wealth to your children and grandchildren.
Surely that money should benefit your family for generations to come.
Yet history suggests otherwise.
Across cultures, there is a surprisingly common saying:
“Shirtsleeves to shirtsleeves in three generations.”
The first generation builds the wealth.
The second generation maintains it.
The third generation loses it.
Why does this happen so often?
And why do so many lottery winners, celebrities and professional athletes end up facing financial difficulties despite receiving more money than most people will earn in an entire lifetime?
The answer may have less to do with money and more to do with human behaviour.
Most people believe preserving wealth is primarily a financial problem.
They assume success comes from:
- Choosing the right investments
- Hiring the best advisers
- Minimising taxes
- Structuring an estate efficiently
- Generating higher returns
These factors certainly matter.
But they often miss a deeper truth.
The biggest threat to wealth is not usually poor investment performance.
It is poor behaviour.
Behavioural finance teaches us that money does not eliminate human weaknesses.
In many cases, it amplifies them.
When wealth is transferred without the corresponding skills, habits and values required to manage it, several behavioural challenges emerge:
Lifestyle Inflation
As people become accustomed to higher levels of spending, those lifestyles begin to feel normal rather than luxurious.
Present Bias
Immediate gratification often becomes more attractive than long-term stewardship.
Overconfidence
People who inherit wealth may overestimate their financial abilities because they have not personally experienced the process of building wealth.
Loss of Purpose
Those who receive substantial wealth without earning it may lose some of the motivation, discipline and resilience that helped create the wealth in the first place.
In short, wealth is often transferred faster than wisdom.
The Behavioural Insight
Through my conversations with clients and my own investing journey, I have noticed something interesting:
Money tends to magnify existing behaviours rather than change them.
A disciplined person with money often becomes more disciplined.
An impulsive person with money often becomes more impulsive.
This helps explain why sudden wealth can sometimes become a burden rather than a blessing.
Many people assume that financial security comes from having more money.
But financial security often comes from developing the behaviours required to manage money wisely.
The Value Steward perspective is simple:
Wealth preservation is rarely an investment problem.
It is usually a behavioural problem.
When thinking about wealth transfer, I find it useful to consider three forms of capital.
1. Financial Capital
This includes:
- Cash
- Investments
- Properties
- Businesses
- Insurance proceeds
Most estate plans focus heavily on this form of capital.
2. Human Capital
This is the ability to create wealth.
Examples include:
- Skills
- Education
- Work ethic
- Knowledge
- Decision-making ability
A person with strong human capital can rebuild wealth even if it is lost.
3. Character Capital
This is often the most overlooked form of capital.
It includes:
- Discipline
- Patience
- Delayed gratification
- Responsibility
- Humility
- Stewardship
Financial capital can disappear surprisingly quickly when human capital and character capital are weak.
The families that successfully preserve wealth across generations tend to pass down all three forms of capital—not just money.
Consider the case of retired professional athletes.
Many earn more money before age 35 than most people earn in an entire lifetime.
Yet financial difficulties among former athletes are surprisingly common.
The reason is not a lack of income.
It is often a mismatch between income, spending habits and financial stewardship.
A lifestyle built around luxury homes, expensive cars, private travel and a large entourage can be sustained while millions of dollars are flowing in every year.
The challenge comes when the income slows or stops while the spending habits remain.
Former boxing champion Floyd Mayweather provides an interesting example.
Throughout his career, he reportedly earned hundreds of millions of dollars and became known worldwide as “Money” Mayweather.
Yet reports later surfaced suggesting that he faced significant financial and legal challenges, including a federal tax lien of more than US$7 million for unpaid taxes.
Whether Mayweather is ultimately wealthy or not misses the larger point.
The behavioural lesson is that high income does not automatically create financial security.
Money can solve many problems.
But it cannot solve problems of discipline, delayed gratification and stewardship.
The same principle applies to lottery winners.
Someone who builds $5 million over 30 years develops financial knowledge, investing experience and decision-making skills along the journey.
Someone who wins $5 million tomorrow receives the money immediately, but not necessarily the wisdom required to manage it.
The money arrives faster than the capability.
This is also why some families choose to use trust structures rather than leaving a large lump-sum inheritance.
Instead of transferring $2 million outright to a beneficiary, a trust may distribute income gradually over time or release funds only for specific purposes such as education, healthcare or housing.
The objective is not control.
The objective is protection.
A trust acts as a behavioural guardrail.
It recognises a simple reality:
People often make their biggest financial mistakes when they have unrestricted access to large amounts of money.
If you are thinking about legacy planning, consider asking yourself these questions:
For Parents
- Am I teaching my children how money works, or merely planning to leave them money?
- Have I discussed investing, budgeting and stewardship with them?
- What values do I want my wealth to reinforce?
For Investors
- Am I developing financial skills alongside growing my portfolio?
- Would I know how to manage significantly more wealth if I suddenly received it?
For Families
- Does our estate plan transfer wealth, wisdom or both?
- Are there structures in place that encourage stewardship rather than consumption?
The goal is not simply to leave behind assets.
The goal is to prepare people to manage those assets responsibly.
The greatest inheritance is not money.
It is the ability to manage money.
Wealth can be created in a generation, but preserving it often requires passing down discipline, values and good judgement alongside financial assets.
Because wealth rarely disappears in a spreadsheet.
It usually disappears in human behaviour.
If you could pass down only one thing to the next generation, would it be money—or the wisdom to create and manage money?
