We do long-term forecasts going up to 2030, and basically show the slowing trend of labour force growth over that period. So the first symptom would be you'd see all the boomers getting ready to retire; they'd leave the workforce. They'd maybe work half-time, but you'd have a lot fewer hours worked and overall labour force growth would slow.
As Benjamin was saying, that has a deadening impact on the overall economic growth potential. It's happening already; you can already see it happening in various parts of our economy. That's probably the reason why the unemployment rate didn't jump as high as in the last two recessions. It is that employers were worried about the fact that they wouldn't be able to find new people in the recovery period we're now in. But it's very evident if you look at the demographics that we'll be facing that slowing impact. We've seen it over the last five to eight years and we're going to see it going forward now.
