A good banking system allows the savings of the citizens to be aggregated and lent out to the government and productive companies.

Bianco Research published a truly epic chart pack clearly illustrating the current and future disaster that is the US banking system. You are in the denominator too, just like a red-blooded Jane Doe American schmuck.
