If you’ve been watching global markets over the last decade, you’ll notice a pattern that rarely makes the headlines but quietly shapes the way wealth moves; and who gets to benefit from it.
Across the world, the wealthy are pouring more of their money into unproductive assets: things that safeguard wealth, but don’t create value. Bitcoin? Soaring. Gold? Persistently climbing. Luxury cars, art, and rare collectibles? Tripling among ultra-rich investors who buy them not for use, but to park wealth and sell later.
Even in Egypt, the National House Price Index tells a clear story: housing prices rise far faster than incomes or productive capacity; yet many properties sit idle. They’re not homes. They’re vaults.
A recent analysis presented in a Brown Bag Seminar by Sebastian Ille, associate professor of economics at Onsi Sawiris School of Business, highlights a striking insight: where wealth is stored matters just as much as how much wealth exists.
And increasingly, it’s stored in places that don’t grow economies.

Productive vs. unproductive assets, and why the difference shapes our future
Let’s break it down simply. Productive assets generate real value. Factories,office spaces, and farmland are just some examples. They produce outputs, returns, jobs, and innovation.
Unproductive assets, however, do not. They store wealth. They look impressive, but they don’t produce anything.

The irony? Unproductive assets can make owners richer, while making economies poorer. Unproductive assets create wealth through speculation, but render an economy more volatile.

The big questions economists are now asking
Ille and other economists are pushing us to confront three deceptively simple questions:
What happens to an economy when more people invest in unproductive assets?

The answer is not straightforward: On the one hand, the investment in unproductive assets can reduce investment in capital which leads to slower growth, weaker productivity, and less job creation. On the other hand, gains from speculation can free financial resources that can be reinvested in productive capital. The shifts in investment between unproductive and productive assets, however, lead to business cycles of boom and bust periods, and in the worst case, to wealth destroying speculative bubbles. Ironically, investment in unproductive assets can therefore both decrease and increase economic output but generally leads to a more volatile economy.

How does this shape total wealth and inequality?
The increased volatility in economic output and potentially immense speculative gains generally favor wealthy investors and are detrimental to those who have less access to money. Speculative bubbles also tend to redistribute wealth from the poor to the rich.

Here’s the twist: productive assets actually outperform unproductive ones, just not immediately
Over the long term, productive assets are consistently stronger, more resilient, and more valuable. They survive recessions better. They create purchasing power. They multiply rather than sit idle.
Unproductive assets? They’re high-risk, prone to bubbles, and offer no income or utility while you own them – they need to be sold to create returns and their value depends entirely on what the next buyer is willing to pay.
While the wealthy rely on the support of professional investors and are therefore better in predicting price dynamics as well as are able to spread risks across various assets, those with little wealth tend to invest in unproductive assets to late (thus at too high prices) and sell to early (thus not materializing enough profit).

Capitalists vs. Workers: why the system widens gaps by design
Ille’s work reminds us that not all people can make equal use of the different types of assets and don’t have the same information to optimize their investment. .
Wealthy investors can better spread their investments between different productive and unproductive assets. They are therefore less vulnerable to price fluctuations. In addition, their costs of investment are lower because they generally possess more collateral. Those with lower wealth often save less (since a higher share of their income is used for consumption) and demonstrate higher risk aversion. They also have fewer opportunities to spread their investment and less access to financial information. They therefore tend to follow the crowd — a behaviour economists call herding assuming “the wealthy must know what they’re doing.” But workers then often enter the market late, at worse prices and are obliged to sell earlier.

This creates a structural inequality engine: The wealthy can more strongly benefit from speculative assets. Workers follow them, even though they can’t hedge risks. Productive investment falls across the economy which negatively affects wages and therefore the opportunity of workers to invest. As growth becomes more volatile, workers see their wealth reduced while the wealthy accumulate more wealth – and the wealth gap increases.

A different path: what happens when we reward real value creation

Here’s the hopeful part. When capital owners are incentivized, through policy, regulation, or market opportunities, to invest in productive assets, everything changes: Economies grow more sustainably . Wealth becomes more evenly distributed, while economic volatility decreases. Business cycles become less pronounced as growth becomes more inclusive as well as more stable

Redirecting wealth from speculation to production is the difference between an economy that survives, and one that transforms.

The human bottom line
Economic models aside, this is fundamentally a story about who gets to dream and who gets left behind. Because unproductive assets don’t just hoard money, they hoard possibility.
When wealth sits in empty houses, rare paintings, and speculative tokens, it doesn’t build factories, create jobs, or open doors. It doesn’t give workers mobility. It doesn’t drive innovation. It doesn’t create dignity.
But when wealth flows into real, productive assets, economies don’t just grow, people grow. And that is the choice every society has to make. Do we want wealth that sits? Or wealth that builds?
