If you look at the growth, in terms of our population and the age of the labour force, it's rapidly declining. Glen said that by around 2012, if you are looking at growth, the growth will be occurring from immigration, not from our natural population. That is the net growth in terms of labour force.
There is an issue you mentioned. You associated labour shortages with the aspect of being an export nation. There are other things that need to happen, as well, so that we continue to prosper as an export nation.
We refer to three components. We've already mentioned investing in terms of our human capital--training programs, and so on. The second has to do with investment in new technologies. We do poorly compared to other countries in terms of that. We don't invest as much. That's what we call, in economics, capital intensity. We're much lower than what we are seeing in other countries, which is affecting our productivity.
The third critical element is the degree of innovation and commercialization that we have in this country, which helps us become more efficient but also helps us figure out ways of producing higher-value types of products with the resources we have--our human resources and our machinery and equipment.
There are a lot of other things that we can do to make sure that we continue to prosper.
