I'll just comment on what Roslyn Kunin said in that respect. We do have a very tight labour market right now. I am not quite so convinced it will always stay that tight. We're having a boom. The American economy is doing well. I think we could well have changes. We won't before the Olympics, but I'm not at all certain that we won't have downturns. So I have doubts about the endless progression. That does not usually happen in most economies indefinitely.
I'm not sure I answered your specific question.
