Sorry to interrupt, but you haven't seen it yet because it's only going to happen in 10 years. The shift is going on now. It didn't happen in the 1960s or the 1970s. You have the baby boomers retiring now, so shouldn't we be waiting to see? Most of the people who have been hired in the last 10 years will last a good 30 years, won't they? I hate to use the expression “last”, but they'll be working productively for the next 30 or 40 years.
On March 29th, 2007. See this statement in context.
