Let me break this into two questions.
What I said earlier is that, relative to other countries, our system works pretty well. If you think there are countries around the world that didn't have a problem with 2008, and where the pensioners are fine, give me the list at some point, because I'm not aware of them.
Second, let's understand what we're talking about here. There's the pension system and then there's the economic system. What we had in 2008 wasn't a pension crisis; it was an economic crisis. It was a financial markets crisis. It took all the assets down.
Most pension systems are built on retirement savings, retirement savings in the sense that they have big pools of assets, and the bigger the pool of assets you had, the more money you lost in 2008. The big plans lost money and the little RRSPs lost money. The only people who didn't lose money are the people who invested entirely in government bonds.
If the question is about what people have to do to avoid a recurrence of 2008, it's to have a pension system built entirely on government bonds earning 4%. The problem is that this turns out to be a safe but unaffordable system. If you work out the cost of good pensions with 4% returns, you get, like the federal public sector plan, 34% of pay.
Most people don't think they can afford to pay 34% of pay for a pension plan. So you have to decide at some point whether you're going to learn to take the risk and deal with the risk, or whether you want to avoid the risk. If, as most systems do, we decide to take the risk, one of the things you have to resign yourself to is that when those very rare years come along, like 2008, there will be problems.
