The $124 trillion question: Preparing for the greatest wealth transfer in history

We sit down with Mike McGrann from BBH’s Center for Family Business to discuss preparing the next generation for the largest wealth transfer in history and what readiness for this transition truly means.

Let’s start with the age-old existential question: Does money buy you happiness?

It does to an extent. At a certain point, it does not. I recently came across a quote that resonated with me:

"[I]nherited wealth does not conform to common economic theory, where an individual’s happiness increases when their benefit, like income, is maximized and their cost, like work, is minimized. … [W]hile small inheritances did increase well-being, large ones did not."1

That quote captures what we’re talking about today.

Aside from the sheer size of the upcoming wealth transfer to the next generation – $124 trillion – what makes this transfer different from previous generational transfers?

The two differentiators are the breadth and the depth of this transfer.

The amount of wealth created by baby boomers is unprecedented in the history of the world. Compared with 1989, when those over 70 held 19% of wealth, older individuals now hold roughly 31% of U.S. wealth. That share drastically outsizes the shares of preceding generations.

At the same time, the number of high-net-worth households is growing drastically. The U.S. has approximately 24 million millionaires, the largest concentration of wealth holders globally. In 2024 alone, the U.S. added 379,000 millionaires.

The scale of this transfer is historically unique.

What’s the biggest misconception younger generations have about inheriting wealth?

I wouldn’t say there’s one universal misconception. What I often see with younger generations is a lack of clarity.

Many younger family members don’t know how much they are going to inherit, often intentionally. They also often don’t know what the expectations attached to that wealth are. What are the boundaries? What does inheriting mean from an economic and psychological perspective?

From my experience, there is incredible ambiguity within family systems about what inheritance means. That ambiguity is one of the biggest drivers of conflict. This is why it is so important that parents initiate conversations about wealth and help their children understand their intent for their wealth, so that they are ready when the time comes.

What does “being ready” to inherit wealth actually mean?

Being ready means understanding the expectations and boundaries. Who has control? When do you have access to it? When do you not?

At the deepest psychological level, being ready means building a sense of purpose that is independent of the wealth of your family.

One of the biggest challenges with inherited wealth, which is very different from earned wealth, is integrating it with your identity. Some people reject their wealth entirely. They distance themselves from it and feel embarrassed by it – that is complete rejection.

On the opposite end of the continuum is complete and total entitlement. A challenge for folks across the continuum is acknowledging wealth as a wonderful gift that doesn’t define them as a human. How do you do that? You develop an independent identity. Acknowledge it as a part of your life, but don’t let it become all of your life. Take risks, pursue wild goals, and find your purpose.

How does gender play into these conversations?

Research shows differences in how wealth affects men and women.

Because of longstanding gender stereotypes, often self-imposed, it can be very difficult for men who marry into wealth to feel confident when their earnings are a fraction of their spouse’s family wealth.

I’ve seen situations where a future husband initially feels comfortable with that dynamic, but overtime it becomes challenging. Wealth doesn’t just impact the inheritor; it impacts your relationships.

Why does inherited wealth come with restrictions?

It's a somewhat flawed analogy, but we don't let 14-year-olds drive cars because they’re not ready.

Inherited wealth is similar. At 14, you’re probably not ready to drive. At 21, you’re probably not ready for substantial inherited wealth either.

That takes time, and receiving substantial wealth of any kind too early can cripple that. Unbounded wealth is very capable of crippling that process. At what age is it appropriate? It depends. But that is a conversation that needs to be had between parents and their kids.

We require education before issuing a driver’s license because it reduces accidents. There is no standardized form of “wealth education,” but if you want the next generation to be successful stewards of wealth, it requires transparency, dialogue, education, and boundaries.

Mike, thank you so much for your time.
