Normally you combat inflation by increasing the interest rate. But with a debt of 30 trillion, the US is constricted in how high those interest rates can go. If the interest rate went up by a mere 2%, the increase alone in interest that the US would have to find would be 600 billion dollars each and every year. (Or almost as much as the huge overblown Defense Budget). So what is the US going to go without? Its Military or its interest rate rises?
Those interest rates won't be going anywhere. That means that inflation is going to hit levels almost unthinkable.
