It's one approach. One of my concerns with it would be that the Canada Pension Plan in many ways isn't really a pension plan. It's a kind of hybrid vehicle that provides disability insurance and pension income insurance and that started out as a pay-as-you-go system and then was transitioned into a funded system. It really operates under a very delicate balance right now. If you wanted to increase the earnings dropouts for people, then you would need to increase the contribution rates.
I'm not saying it's a bad idea, but I bear in mind that Canada Pension Plan benefits are not very large, and they are determined by reference to earnings. I'm not sure this would be a complete solution to the problem Ms. Smith raises.
