Let's work together on this. 
Raising money by selling T-bills is borrowing. Now, my first wife used to say that if we're broke we can always buy stuff w/ our credit card but eventually I found out that I still had to pay the credit cards for every penny borrowed plus interest.
<<<This is what us tax payers have been paying every year on federal interest.
The current quarter $T is every bit as high now w/ near-zero rates as it was a decade ago when T-bill rates were 6%. President Trump will be having to come up w/ $trillions for his interest payments.
