Thank you for your continued interest in lending money to the United States government. We appreciate your concern for us during this trying time.
I feel obliged to make you aware of the following:
We have no money to repay any more of your loans.
Our current options are to raise taxes, print more money, or default on your loans.
Raising taxes is politically unpopular, therefore none of our leaders will ever raise enough taxes to repay your money.
Printing money causes inflation, and you wouldn't want that devalued crap anyway. Plus, inflation is a guaranteed regime-changer, and our current Gang Of Thieves enjoys being in power.
Therefore, if you give us any more money we aren't going to give it back. It's that simple. We'll have to default.
(I've helped friends write similar letters to this one, usually involving their 16-year-olds and too many credit cards. Our present circumstances aren't much different.)
Thank you for your kind attention to this matter. If you have kids of your own, you know what it's like.
