I think the two major virtues of expanding the Canada Pension Plan are that there would be an increased employer contribution as well as an increased employee contribution; it would be mandatory on both sides. I think there is a lot of evidence that if you leave it to individuals to save on a voluntary basis, they will not save enough for retirement. We can debate the merits of those.
The second key point would be that the Canada Pension Plan is an extremely well-run pension plan at very low cost, and we'd certainly be very concerned that while PRPPs may have a somewhat lower cost structure than individual RRSPs, they're still going to be higher-cost. I hate to take a shot, but there is a considerable amount of profit earned in the financial sector from running these plans, and we can really reduce that through a public sector alternative.
