Piketty’s Formula of Inequality: An Overview and Critique

Thomas Piketty’s inequality formula, r > g, argues that when the return on capital (r) consistently exceeds economic growth (g), wealth inequality grows because the rich accumulate wealth faster than others. This dynamic, according to Piketty, is a natural consequence of capitalism and leads to rising inequality over time.

However, critics, such as Larry Summers, argue that Piketty underestimates the diminishing returns on capital. As capital accumulates, its returns should decline, and Piketty may have misinterpreted the literature regarding how quickly this happens. Summers also highlights that depreciation—often overlooked by Piketty—reduces the net returns on capital, making the gap between r and g less significant than Piketty suggests.

Addressing inequality requires policies that promote fair capital distribution, progressive taxation, and investment in inclusive economic growth to ensure a balanced society.

However, practically, Piketty’s r > g argument has strong support, especially when considering the real-world dynamics of capital accumulation. Wealthy individuals can easily invest in assets like real estate, stocks, and even lend money at interest, which provides them with higher returns compared to wage growth. This allows the rich to accumulate wealth at a faster rate than the economy grows, reinforcing inequality.

Globally, there are always emerging opportunities where strategic investments can still yield strong returns, so the decline in returns may not apply uniformly across all asset classes or regions. This diversification helps maintain higher returns over time, countering the potential for diminishing returns in any one area

In reality, while diminishing returns may occur, the wealthy still have a structural advantage in accessing high-yielding investments, making Piketty’s argument more reflective of current inequality trends. The persistence of wealth concentration through capital appreciation in real estate and stocks suggests that Piketty’s concern about widening inequality is relevant.

In addition, Inequality shouldn’t be examined solely through the lens of Piketty’s formula (r > g), which focuses on the accumulation of wealth by those with capital versus those without. It’s also essential to consider the sources of wealth, the legality, and whether unfair advantages—such as corruption, lack of integrity, or exploitation—play a role in that accumulation. Wealth that stems from unethical practices exacerbates inequality further, undermining fair competition and contributing to systemic injustice. Including these factors provides a more comprehensive analysis of inequality.
