Not all defined contribution or defined benefit plans are created equal, but I think it can be possible to have quite good defined contribution plans. We've seen that in countries like Australia and the U.K. that have set up public defined contribution plans. Saskatchewan has a public DC plan as well.
The challenge is in how you manage that liability. You could look to the example of Saskatchewan, which is still managing the stranded liability associated with setting down its DB plans. That occurred, I believe, in the late seventies, and Saskatchewan will be managing that liability for nearly a century from now. It remains on the books.
Those are the complexities that I think would need to be worked through in a structured process to figure out what is actually the bottom line associated with these different options and how much retirement security for the dollar each of the options deliver.
