In 1820, the vast majority of people lived in extreme poverty and only a tiny elite enjoyed higher standards of living. Economic growth over the last 200 years completely transformed our world, with poverty falling continuously over the last two centuries. This is even more remarkable when we consider that the population increased 7-fold over the same time. In a world without economic growth, an increase in the population would result in less and less income for everyone. A 7-fold increase in the world population would be potentially enough to drive everyone into extreme poverty. Yet, the exact opposite happened. In a time of unprecedented population growth, we managed to lift more and more people out of poverty.

In 1990, there were 2 billion people living in extreme poverty. With a reduction to 705 million in 2015, this means that on average, every day in the 25 years between 1990 and 2015, 137,000 fewer people were living in extreme poverty.

Socialism didn't do that. Capitalism and liberalism did.
