I came across this site by Anup Shah that has a detailed look into the causes of poverty. I found some of the statistics he shows to be very embarrassing and a shameful reflection on humanity today.

* Half the world — nearly three billion people — live on less than two dollars a day.

* The GDP (Gross Domestic Product) of the poorest 48 nations (i.e. a quarter of the world’s countries) is less than the wealth of the world’s three richest people combined.

* Nearly a billion people entered the 21st century unable to read a book or sign their names.

* Less than one per cent of what the world spent every year on weapons was needed to put every child into school by the year 2000 and yet it didn’t happen.

* 1 billion children live in poverty (1 in 2 children in the world). 640 million live without adequate shelter, 400 million have no access to safe water, 270 million have no access to health services. 10.6 million died in 2003 before they reached the age of 5 (or roughly 29,000 children per day).

Anup Shah shows us the institutions, policies and people behind many of today's causes of poverty.
