In a fractional reserve banking system money is created when a loan is made. Thus when Congress takes out a loan for a trillion dollars that money is injected into the economy and as it passes through banks who also make loans there is even more money created. This is considered a feature of fractional reserve lending by the mainstream. Austrian economists consider it a bug.
