Wikipedia - even if it is the 2010 numbers, it isn't that much different right now. I know it has to do with productivity, but that is why the GDP is a good measure: if you have a higher GDP, you produce more. Ergo, the numbers being about equal in Italy and the USA means that they are about the same amount in debt by means of being able to pay it back - except that the sheer amount of the US debt can have a way more desasterous impact in case the debt will grow to the extend that everyone sees it won't be repaid. Also, there is no power on earth which could bail out the USA. Italy though is way less system critical and can be bailed out undr certain circumstances, at least partially. There is a lot of wealth amongst the people though which could be invested. Part of the Italian problem is that small business owners do not reinvest into the comany and don't thrive the grow but rather stagnate. Corruption and organized crime on the other hand are problems Italy is facing in higher per capita rates than other first world countries... The USA has the highest expenses for military per capita or GDP or in % of budget. This does not really create revenue though. As I stated, the problems are different.
