“We know that poverty is not inevitable because poverty has declined very substantially in many countries. The population of Denmark was once as poor as the population of Ethiopia today, but since then poverty declined and living conditions improved: average incomes increased more than 25-fold, the child mortality rate declined from more than a quarter to less than half a percent – one of the lowest levels in the world – and Denmark is today one of the countries where people report to be most satisfied with their lives.” Max Roser with a very interesting, very graphical look at how much economic growth is necessary to reduce global poverty substantially.
