Well that's just what it has done. You can't define "reasonable" any more than you can turn lead into gold.

It did. Now you have to define "start to appear". Try to hit that moving target.
Greenspan said there was no moving target. I suppose one is always entitled to the perspective that central bankers cannot see the trucks that will run them over until it is too late. Why have them then?
