To go back again to income splitting, the government itself has estimated that it is going to spend $3.6 billion over the next six years on income splitting just for retirement income. We can do a gender analysis of that and see where that benefit is going to end up.
In the paper I did for Status of Women Canada, on page 56 in English and on pages 65 and 66 in French, for anyone who may want to look at it later, I have used micro-simulation software to model the effects of income splitting for retirement-aged people and for people of all ages. Clearly, just by changing to income splitting of retirement income, women's share of income will go down farther than it has gone down now.
I hope that's a sufficient answer.
