Some screamer on CNBC started a great analogy which we can keep extending:
You are driving along a highway, someone decides they need to fix a part of it which did not need fixing and diverts you down a badly constructed bumpy temporary detour. When you get back on the highway, they throw some spikes on the road.
But fear not, there are a couple of ambulances on stand by, which may or may not take you to a hospital that you may or may not be able to afford. The spikes may or may not work and may or may not blow up your car.
