Let me jump in there, because I see a bit of an inconsistency in some of the things you're arguing.
Certainly, arguing for larger deductions or contribution limits for RRSPs clearly favours higher-income earners. Today, I believe, 93% of all RRSP contributions go unmade; we have only 7% of contributions that are made. That seems to be a very blunt instrument of taxation policy that is not accomplishing, really, any goal right now. So I see an inconsistency there in your argument.
But I wanted to ask you as well about RESPs. We've had a big debate here in Parliament about whether RESP contributions should be tax-deductible or not. Can you give us an academic viewpoint on your position on this?
Perhaps, Professor Davies, you could chime in as well.
