Yes, I was just going to add to that. By looking over a longer horizon, as you're aware, the demographics suggest that the growth of the labour force is going to be declining. In fact, it's already started. Effectively, workers are aging. We're all having fewer babies and so the workforce is growing more slowly.
When you look, going forward, increasingly, the challenge will be finding enough good workers for the jobs, so that's going to be partly related to skills.
I would add the need to increasingly improve efforts to tap into areas of the workforce where there's potential for more growth. For example, we're living longer, we're healthier, and the labour participation of older workers is going up. There is scope for that to go higher with more flexible work arrangements.
The aboriginal population is growing rapidly. There are lots of good reasons to improve access to work for aboriginals. The coming demographic squeeze is just another one. Those are a couple of examples, and immigration, yes.
