What a wonderful article. I think that there are two sides to this coin: the nature of the debt and the nature of the repayment. Even the smallest and most well mannered debt is a problem if there is no path to repayment. And even large, nasty debt is ok as long as the people borrowing have done their homework and have a solid plan to repay. So this article did a great job of profiling the debt but it didn’t go into enough detail about the borrowers. If interest rates have been so low, and the borrowers have been somewhat lucid, even this large debt can be paid off without any crisis?
