the 600% interest works like this.

these countries take out the loan. most for defence (or attack). for obvious reasons this money isn't able to be paid back immediatly as fighting wars doesn't bring in the money when you are importing everything needed to fight it.

so the interest kicks in. and it's high. the country though is now recovering from a war and so still has problems to face before it can pay back the loan. so the interest and amount grows again (interest upon interest). to successfully pay back a now very large loan the countries must industrialise or get more effecient but this requires more money. which they don't have. in fact they now have less money because the banks are now taking money out.so your country stagnates and grows poorer.

but you still ain't keeping up with the loan repayments so the amount owed grows and grows. and still you have no money to reform. and so this process goes on til you are in nigeria's situation of having paid back the loan many times over but still owing far more.

expotential interest is one of the reasons (beside subsidies/tarriffs and lack of aid) is why 30,000 children died yesterday, today and will die tomorrow.

and if wanting to end that for the sake of loans that have alread been paid back and money earned many times is getting all john lennon then forgive me.

but i for one will not be part of the most effecient genocide this world has ever seen. you may be content with that.
