You clearly haven't taken an econ class and if you did graduate from college you should ask them for your money back!
If you want to "prove" to me that the U.S. is owed far more money than it owes I'm all ears. If you want to "prove" that interest rates are lowered to control inflation, again I'm all ears. If you can do neither, then just shutting up would be best for everyone, you included.
Graduate LOL I'm a Brit, we don't do that, come on try harder

Maybe the US doesn't care about what it owes as it has no intention of paying, but people in charge make money from people owing money and paying interest ??
100% defo interest rates are used to control inflation, it's literally the only thing they have that controls inflation.
No Econ BS class needed, I'm just old and wise and don't believe most of the crap you lot are fed in Econ classes and the like.
