The debt crisis:

“this issue should have been resolved years ago.

For at least 20 years we have known that heavily indebted poor countries (the HIPCs) are unable to repay their debts... 

the debts should simply have been cancelled... 

in fact rich countries should have given the poorest countries grants rather than loans so that the poor countries would never have been indebted in the first place"

(Jeffrey Sachs)
