Dear DUmmies:
Imagine a business which has revenues of $1 Million per year. Not bad, right?
Now imagine that same business has: 1--operating expenses/expenditures of $1.8 Million per year, and debt of over $7 Million, with assets that don't even come close to covering debts.
You know what that business would be called? BANKRUPT. If you were a bank, would YOU loan to this business? Of course not. But this being the US government, it doesn't need a "loan" per se. It just prints up more money, and damn the consequences.
Now you know why we are so concerned.
