When you think of the fact in the introductory comments that people used to retire at age 65 and die before age 70, it's not that we're recommending that, but we have increased our lifespan massively. Again, that's a good thing. But when you look at the math of these pension plans that were put in place, it's not only longevity; it's decreasing retirement age, notably in the public sector. It's not changing in the entrepreneurial sector; it's exactly the same retirement age as it was 30 years ago, age 66.
I do think it's something again where, if you phase it in over time, it doesn't have to be terribly punitive. There will be opposition. Of course there will be opposition. That's one thing.
The other element that hasn't even been mentioned is health care costs. When you see a lot of pension plans and some of the defined benefit plans—again, notably in the public sector—they have health care elements attached to them. That is also going to up the costs, because health care costs, as we know, are going nowhere but up.
So there are a lot of reasons we really should look at increasing the retirement age. That's one part of it, but it's not the only part of it.
