Extreme poverty is result when nation government and individuals act only to promote and protect self interest; for instance, governments of wealthy countries give low priority to end world poverty cause they are democratically elected and must cater to their voters.
However, they prohibit farmers in poor countries for selling their products in rich countries in order to prevent farmers in rich countries from losing business. Perhaps rulers of rich countries heavily subsidize their farmers to help them outsell farmers in poor countries.
Clearly, the cause of poverty is the tendency of people and governments to protects their personal interests is only because man has dominated every where with injustice.
