No, RRSPs are to incentivize saving for retirement.  But especially given that they already disproportionately help those in the higher tax brackets and do nothing for the large numbers of people in the lower income bracket, I don't believe the maximum contribution should be increased.  We be better off finding a way that low income people can save more for retirement to reduce the need for government to supplement retirement income to the degree they do, which is basically what they're aiming to do with increasing CPP contributions/benefits.
