This document discusses inequality through several charts and data sources. It shows that while the percentage of people living on less than $1 per day has declined globally, income inequality has increased in the United States with the top 10% earning a larger share of income. However, while inequality exists, consumption and technology ownership has increased even for low-income households in recent decades.
