After the 2008 crash and QE was begun, Fed Chairman Ben Bernanke said he wished he could drop money out of a helicopter directly into the hands of the American people, thus earning the nickname "Helicopter Ben".
QE was giving money to the banks instead of the people. And the banks buried the money in their back yards instead of lending it out. So we had no inflation.
Well, the federal government finally launched the helicopter last year and gave everyone stimulus money directly. And America went on a spending spree. So now we have inflation.
I think what the Fed is waiting for is for us to run out of that money and for spending to slow down.
If that happens, and it probably will, inflation will come down commensurately.
That's what the Fed is waiting and hoping for.
