If we get this done quickly, we can get to the point where side-lined money will be willing to get back in and start the economy anew. It will be more violent and painful at first, but we can get through it and not prolong the pain.
If we drag things out, unemployment will skyrocket, and jobs will be lost for many years to come, rather than just 1-3 years in a quicker correction, IMHO.
