In debitum incrementum?A country’s national debt, also known as government debt or public debt, is defined as all borrowings owed by the government of a country. It usually comprises internal debt – owed to other governmental departments – and external debt, which is held by the public and is owed to government bond owners. National debt can be caused by a struggling economy in general, or by low tax income, which usually leads to money being borrowed from other governments for support, which in turn cannot be paid back right away. At first glance, a high national debt is not always a sign of a struggling economy – but since increasing debt can slow down economic growth significantly, it is imperative for the respective government to seek a steady reduction in the long run.
