I think that, if you increase the clawback, it would be a less bad way of going about doing things. On the sustainability thing, we're phasing in this increase in such a way that it really only applies when the cost of OAS peaks, so it doesn't really make that much difference to the cost of the program. The average person of 65 is going to live past 80, so you're cutting off two years. It's not a huge percentage point reduction to the cost of the program.
What I would say is that I would not ignore the importance of OAS to people who aren't in a very low income situation. We know that baby boomers, or a significant section of middle-income baby boomers, aren't saving enough for retirement. CPP and OAS in combination replace 40% of the average wage, which is a very low public pension compared to the great majority of OECD countries. So there are a lot of couples who are going to lose a significant chunk of change, the ones who are fully affected by it. I guess basically they're going to have to work that much more to make up the difference, or save that much more, but we know people are having trouble saving.
I'm not sure whether the real motivation for this is the cost or the view that people are retiring too early. To my mind, there are all kinds of positive incentives we can put in place for people to continue working past 65 and to encourage employers to retain workers. We could talk about all those things, if that's what the debate is about.
