The Millionaire Next Door: Wealth vs Income, Lifestyle-Inflation and Long-Term Financial Planning

An interview with Sarvenas Enayati and Elham Ettehadieh

In Part 2, Episode 1 of our podcast “Truly Rich”, we touched on key ideas from The Millionaire Next Door, such as the difference between wealth and income and how everyday spending habits influence long-term stability.

In this article, we continue the conversation and examine how steady, consistent habits in wealth building can shape long-term financial stability.

“What is The Millionaire Next Door really about?” 

Sarvenas Enayati: Elham, when people hear the title The Millionaire Next Door, they often think it’s about becoming rich quickly. Is that what the book is about? 

Elham Ettehadieh: Not at all. The book is less about “getting rich” and more about understanding the difference between wealth vs income. Many people earn well, but their net worth vs salary tells a different story. The authors show that wealth is often built quietly, through consistent decisions, especially around spending, saving, and long-term planning. 

It’s about how everyday spending habits and wealth building are connected. Not glamorous or loud. But consistent. 

“Why doesn’t wealth always look wealthy?” 

Sarvenas: One of the strongest ideas in the book is that wealthy people often don’t look wealthy. What do you think is behind that? 

Elham: Exactly. Many households with high net worth live comparatively modestly. They live below their financial means. They don't necessarily drive the latest car and don't constantly upgrade their lifestyle. What stands out is that they often focus on keeping fixed costs manageable and making deliberate choices about what they spend on. In other words, the goal isn’t to “look successful,” but to maintain flexibility, having options if life changes, costs rise, or priorities shift. 

And that’s important for women today, especially in a world where we are constantly shown what success “should” look like. It can be a useful reminder that financial stability is often built through quiet, consistent decisions, not through visible consumption. 

The chain reaction effect: When one upgrade changes everything 

Sarvenas: In our podcast, you mentioned financial “chain reactions,” for example a series of decisions that are interdependent. What do you mean by that? 

Elham: Yes. Imagine someone receiving a house from their parents. Just the house. Nothing else. Sounds positive, right? 

But if that house is in a very nice neighborhood, something begins. The neighbors all have beautiful gardens — so you feel you must invest in your garden. Then you see the cars parked outside, and suddenly your car feels “not enough.” Maybe all the children attend a certain private school. And you start thinking maybe my child should too. 

One fundamental decision, where you live, can trigger a chain reaction of additional expenses. 

This is what the book indirectly highlights: lifestyle inflation doesn’t always start with income growth. Sometimes it starts with context. With the environment. With comparison. 

And these decisions influence your long-term financial planning more than you might realize. 

Social media and lifestyle pressure 

Sarvenas: Do you feel this has become even stronger in the age of social media, where lifestyle is constantly being sold to us? 

Elham: Absolutely. Today, we live in a world where lifestyle is constantly being sold to us. A mixer promises a better morning. Sportswear promises more motivation. Parenting tools promise happier children. 

When I speak with many women, especially mothers, they often say they don’t even notice how these influences shape their spending. You scroll through reels, and there is always a product placement somewhere. It subtly suggests: “You need this to live well.” 

And this is where status spending becomes relevant. Not necessarily to impress others, but to feel that we are doing things “right.” 

But the book reminds us: building wealth often requires resisting that pressure. 

“Are we happier if we consume more?”

Sarvenas: We are constantly told that we are happier if we consume more, if we experience more. 

Elham: Yes. But the experiences shown are often extreme. Not hugging a tree in your neighborhood, but swimming with dolphins somewhere far away. 

There is nothing wrong with beautiful experiences. The question is: does everything have to be immediate? 

Nobody on social media posts: “Today I didn’t buy something so I can afford orthodontics for my child next year.” You only see the perfect smile at the end. 

But building savings volume often happens quietly. Gradually. Through small conscious decisions. 

A new perspective: Saving can also feel “cool”

Sarvenas: I love what you said in the podcast, that perhaps saving should feel hip again. 

Elham: Yes. If this conversation can contribute to one thing, then maybe this: that we build a community of women who recognise that joy does not always mean immediate consumption. 

You can enjoy life deeply without integrating every advertised product into it. 

Many people underestimate their potential. However, small adjustments to spending and conscious prioritization can often create financial leeway.   

And sometimes the most beautiful joy is anticipatory joy, looking forward to something you are building toward. 

“Is this book relevant for women in Europe?” 

Sarvenas: The book is American. Does it still apply to women in Europe? 

Elham: The tax systems differ. The housing markets differ. But human behaviour is similar. 

The ideas around:

• wealth vs income
• lifestyle inflation
• spending habits
• long-term financial planning 

These themes are universal. 

Women often navigate career breaks, part-time work, caregiving responsibilities, or rebuilding savings after life changes. Understanding that financial stability is shaped by fixed costs and lifestyle decisions, not only salary, can be helpful. 

Building awareness in a consumption-driven world

Sarvenas: If you had to summarize the practical insight from The Millionaire Next Door, what would it be? 

Elham: It’s about awareness. 

Awareness that: 

• Big lifestyle decisions influence many future expenses.
• Income growth does not automatically create wealth.
• Social comparison can quietly increase fixed costs.
• Saving is not deprivation, it is delayed choice. 

The book does not promise results. It describes patterns observed in households who accumulated net worth over time. 

And maybe the core message is this: 

You don’t have to look wealthy to build stability. 

Final reflection 

Sarvenas: And if someone already has a small savings account, or inherited something, what then? 

Elham: Then the question becomes: how do you protect that flexibility? How do you prevent a chain reaction of expenses from reducing it? 

That’s where awareness matters again. Because financial decisions are rarely isolated. They are connected. And perhaps that is the quiet power behind The Millionaire Next Door: It encourages us to separate appearance from substance, and to think long term. 

And maybe the core message is this:
