The author shows us the developing process of the „debt trap". If the accumulated debts cause stagnation, poverty and social tension in the debtor and lower economic growth in the creditor nations, even within the nowadays framework of economic thinking, i. e. if this problem is unsolvable, what can be done? Answer of the author is: the interest rate for the indebted countries must be co-ordinated with their export to the creditor nations and with their own economic growth. The solution is a common interest of the creditor and borrower nations.
