They're not just stand-alone or cumulative over time. They're complex, so that's the overarching conclusion. There is another thing, and I'd like to make that point really clear, because that's the bread and butter of the Conference Board, and I am an economist myself by training. When tough questions like that emerge, many solutions are put forward. The real challenge is to measure the actual real change that a solution will have over time.
We look at the scenarios; we forecast; and we get an indication of the magnitude, but then we have to track that over time and change course. We're dealing with something that, in terms of core structural pressure, is unprecedented.
