What’s in it for me? Gain a deeper understanding of the forces shaping wealth dynamics.

Let’s start with a simple observation: some people have more than others. But why exactly is that?

French economist Thomas Piketty wanted to find an answer that’s backed up by empirical data. In his best-selling and somewhat controversial book Capital in the Twenty-First Century, he thoroughly examined the dynamics of capital and inequality in developed countries since the eighteenth century.

One of the things he found was that the rate of return on capital or r, in the long run, tends to be greater than the rate of economic growth or g – hence r > g. This leads to increasing wealth inequalities unless corrective measures such as progressive taxation are introduced.

In this Blink, we’ll explain the implications of r > g. While this concept is just a slice of the comprehensive insights the book offers, it’s a crucial piece of the puzzle. By the end, you’ll have a deeper appreciation for the intricacies of wealth, inheritance, and the challenges and opportunities they present for our shared future.

When capital outpaces the economy

Imagine a world where two neighbors, Alice and Bob, both plant apple trees in their respective gardens. Alice’s tree, mature and deeply rooted, produces an abundance of apples year after year without much effort. But Bob’s tree is younger and produces fewer apples. Even if Bob tends to his tree meticulously, the natural advantage of Alice’s mature tree means she’ll always have more apples.

In this allegory, Alice’s tree represents capital – assets that yield income without labor. Bob’s tree, on the other hand, represents the general economy. And this simple observation leads to a profound understanding of modern wealth dynamics.

Throughout history, the “trees” representing capital have generally produced a greater return than the growth of the overall “garden” or economy. This difference in growth rates – where the return on capital outpaces economic growth – is the essence of the r > g principle. As time progresses, those who start with more – like Alice – find their wealth accumulating at a faster rate than the economy grows.

The implications of this are vast. Think about a society where a few have deeply-rooted “trees” that continuously bear more fruit. Over generations, this initial advantage becomes more pronounced. While some may argue that wealth is earned through hard work and merit, the reality is that the capital from long-standing “trees” tends to compound and concentrate. This leads to a society where inheritance, rather than innovation or effort, plays an outsized role in determining one’s economic fate.

In such a landscape, the chasm between the haves and the have-nots isn’t just about numbers on a bank statement. It shapes political influence, access to opportunities, and the very fabric of our social contract. It poses a question: In a world that values meritocracy, how do we reconcile with a system where the scales tip in favor of inherited wealth? The starkness of this disparity beckons for solutions, for ways to bridge the widening gap and restore balance to the “garden.”

Inheritance vs. talent

As the seasons change in our allegorical orchard, we find Bob watching as Alice receives a treasured gift: a set of golden gardening tools passed down from her ancestors. These tools, aged yet efficient, enable Alice to cultivate her land with ease, yielding richer harvests. Meanwhile, Bob, equipped only with his basic tools, pours in extra hours, yet his yield doesn’t match up. Alice’s inherited tools, just like her tree, give her a marked advantage. This mirrors how, in the broader economic tapestry, inherited capital amplifies benefits, often diminishing the significance of individual effort and innovation.

While there’s nothing inherently wrong with passing down tools or wealth to the next generation, problems arise when inheritance becomes the dominant determining factor of success, leaving talent and hard work in the shadows. It’s not just about individual stories of Bobs and Alices; it’s about what their stories signify for our collective narrative. As the weight of inherited wealth grows heavier, the stories of self-made successes become fewer, challenging our cherished notions of meritocracy.
