As Alasdair Macleod said in this article: "This is the principal danger to international stability currently posed by the worlds reserve currency, and government finances in the US today are so bad that it has no political option but to continue with monetary inflation in accelerating quantities. Furthermore, the Keynesian mindset justifies this flood of money as the only appropriate response to a stalling economy. These circumstances lead us to conclude that the current emerging period of stagflation can only be followed by hyperinflation, not just for the US dollar, but for all paper currencies. And when inflation rises to, say, thirty per cent, interest rates will be at least in the upper teens or twenties."
