It is a common belief, fostered by economists such as Thomas Piketty, that we live in an age of great inequality. This is partly true in economic terms in some countries. But in more general global terms the reality presents the opposite of this belief.

Excluding the tiny minority of billionaires and dictators, our age is characterised by massively increasing equality. Global data shows that an extraordinary reduction in inequality has taken place in both life expectancy and incomes around the world since 1950.

The chart below shows the gap in life expectancy between the developed countries of Europe and the USA, and the developing countries of Asia and Africa. This gap has narrowed since the end of the second World War at an unprecedented rate. In 1950, life expectancy in China was a lowly 45 years. Today, life expectancy in China is almost the same as that in the USA at over 79 years. Few forms of progress are more beneficial than extended life.
