"Low interest rates stemming from a growing money supply are the only reason the US government has managed to service its gargantuan debt in recent years. The Congressional Budget Office itself has pointed out that even a slight rise in interest rates could potentially result in anywhere from $700 to $900 billion in annual tax payments just to service the interest on our debt. At this pace, paying the republic’s creditors will become our largest government program in no time. Future Americans might go to work and have 50% of their paychecks seized not to pay for government services, but simply to service debt forced on them by central planners.”
