An AI-driven surge in demand for high-bandwidth memory chips has pushed Samsung Electronics and SK Hynix stock prices to record highs [1].
This trend highlights a widening economic divide where the returns on capital are significantly outstripping the growth of wages for the global workforce. As AI technology drives corporate valuations, the wealth generated is increasingly concentrated among asset owners rather than salaried employees.
The rally in the South Korean stock market reflects a broader global pattern of wealth concentration. This phenomenon aligns with the theories of economist Thomas Piketty, who said that when the rate of return on capital exceeds the rate of economic growth, inequality inevitably increases.
Recent statistics from the U.S. illustrate this disparity. In the third quarter of 2023, the share of national income earned by U.S. workers fell to 53.8% [1]. This figure represents the lowest share for workers since 1947 [1].
While wage earners saw their relative income decline, the wealthiest individuals experienced significant gains. Global billionaires saw their collective wealth increase by $2.5 trillion during the same period [1].
To put that growth in perspective, the $2.5 trillion increase in billionaire wealth is approximately equal to the total wealth held by the bottom half of the world's population, which consists of roughly 4.1 billion people [1].
The current market rally in 2024 continues to favor those with significant equity in the semiconductor sector. While the technical achievements of high-bandwidth memory chips are driving industry progress, the financial benefits remain skewed toward shareholders over the workers producing the hardware [1].
“U.S. workers' share of national income in Q3 2023 was 53.8%, the lowest since 1947.”
The disconnect between record-breaking corporate stock valuations and stagnant wage growth suggests that the AI boom is accelerating wealth inequality. By shifting the economic benefit from labor to capital, the AI transition may create a systemic 'deprivation' effect for salaried workers, regardless of the overall growth in GDP or industrial productivity.
