THey can't do otherwise. This is how the system is built. Until we switch onto other solutions to transfer wealth, we're doomed to borrow more to repay more.
If you, as a president, want money in the economy, you have to borrow.
If every country repaid their date right now, there would be no more money left in people's pockets.
I'm not surprised, and the one after Trump will borrow even more. This is what is going to happen.
They could demand zero interest from the FED and forbid fractional reserve lending, problem gone. This is how it use to be done and inflation never exceeded 5 % prior to allowing it or leaving the gold standard. If we also demand it to be backed up by resources like oil and gold, it would not be printable like this, inflation could not be hidden!
So we could fix this right away and just delete the corrupt dept like Iceland did, declare them illegal and now do the steps i mentioned in a night, fixed!
But yeah, there are hinders, humans that do not see this as clear as they should and blame presidents or what ever, they do not run anything. We the population agrees upon this system, we pay our taxes and build the prisons, weapons and banks used to suppress us. We are being used against our selves, no one else is to blame then the tax paying populations!!
