Canadians are not using RRSPs enough, and those that do are in the higher income brackets. The people who need help saving for retirement are those earning under $100,000 -- i.e. most Canadians. So the goal is to ensure that any change has broad effect and target the reasons why people are not saving.
Most Canadian private sector taxpayers are blissfully unaware of the existence of a wonderful bonanza public sector workers enjoy at their expense -- namely, the Canada Pension Plan bridge benefit. But if people were fully informed about the special treatment accorded to public sector workers, one aspect of which being the bridge benefit, they likely would have been less willing to jump on the bandwagon of later retirement for themselves.
