when the national debt is owned by its citizens
-----------------------------------------------------------
无需看上下文,就可以知道这里的owned没有用错,不可能是owed
当国债为其国民所拥有的时候——这有错吗?国家发行国债,国民买国债,从而拥有国债,有毛病吗?
没毛病吧!
Before jumping to the conclusion that there might be typo , just a look at the context in which it occurs and a moment's reflection might have saved oneself much embarrassment and others' some time. hahaha
