Income Inequality Explained: How Skills and Technology Shape Wages

Описание: Income Inequality Explained – Wages, Skills, and Technology
How Labor Markets Create Income Gaps in Modern Economies

Why do some people earn far more than others, even within the same country? This video breaks down the core economic forces behind income inequality, starting where it mostly begins: the labor market.

More than three quarters of inequality comes from differences in wages and employment outcomes. But wages don’t rise or fall randomly — they reflect productivity, scarce skills, technological change, working time, and how well education systems prepare people for modern jobs.

This video explains the key mechanisms that drive income gaps and why the middle of the labor market has been shrinking for decades.
