You've got it backwards. The negative interest is for the lenders, not the borrowers. You give me $100 trillion for a year, and I give you back $98 trillion at the end of the year. I keep the $2 trillion, not you.
I didn’t write it too clearly but I was suggesting tongue in cheek how the gov’t could solve its debt problem.
And the solution was the gov’t borrows 100 trillion and pays back 98.
And it reduces the national debt by 2 trillion dollars.
