The mathematical formula of the operation doesn't make sense either.. The Fed issues money as debt.. and that debt is owed with interest.. So the more money the Fed issues, the more debt is owed.. so eventually more and more debt is created without the ability to ever pay it back. The money that existed at the start of the Fed becomes a finite amount that no longer matters in the formula over time - so eventually the debt goes up and up until everyone but the Fed and its shareholders are poor.
