If I were King for a day and I could change just one thing about governments in general and the U.S. government in particular, I would make it illegal and structurally impossible for there to be any form of government deficit or debt.
Seriously, if you step back and take a look at it, any form of public debt at all is completely immoral. By what right? Public debt is an utterly unethical confiscation of property. Government functionaries who cannot live within sanctioned means are overspending my money and your money without our consent. Without mine, anyway.
Fuck you, government. I hereby formally revoke any implicit consent to be indebted by your sloppy, evil actions. I refuse the debt.
