Question

income equality has
increased in developing economies as manufacturing has decreased.
decreased in the united states as manufacturing has increased.
narrowed within countries but increased across countries.
increased within countries but has narrowed across countries.
not changed in the advanced economies over the past 50 years.

Explanation:

Global income trends show that within most countries (both developed and developing), income inequality has risen due to factors like technological change and shifts in labor markets. Meanwhile, across countries, the gap has narrowed as emerging economies (like China, India) have experienced faster growth, reducing the income disparity between high-income and many low-to-middle-income nations. The other options are incorrect: developing economies with declining manufacturing often see rising inequality; US manufacturing decline (not increase) linked to higher inequality; advanced economies have seen growing inequality in 50 years.

Answer:

increased within countries but has narrowed across countries.
