That looks like a graph of quantitative easing.

To use a car analogy I'm arguing the gas pedal doesn't work as well so the Fed is having to keep their foot to the gas to maintain it's historical speed. Others argue the Fed is has been trying to go faster and that's why their foot is on the gas pedal. The graph seems to support that indeed their foot is on the gas.

Sure, that's quantitative easing. Something that the Fed was not doing in this form before and it's quite controversial whether it has been a success of a failure. In any case, this "temporary" solution is going for over ten years now and the Fed doesn't know how to get out of it.
