Yes. That's a very good question. I think the question that has to fundamentally constantly be asked is who wins and who loses. You need to do that both on income and with respect to gender.
You can be assured the Department of Finance looks at winners and losers, and there are provisions under access to information to secure some of this analysis. Recall that in any cabinet document there's an analysis section that is accessible under access to information, not the recommendations to ministers—they are the confidence of the Queen's Privy Council—but the analysis is and can be used.
To ask the next question, under what circumstances might this change, on the question of income splitting? What happens when there's divorce, when there's breakup? Does this just mean that for tax purposes we move things across and all you're doing is giving a higher tax liability to the lower-income spouse? There are unintended consequences that can happen, so these need to be asked.
Then you need to look at the fundamental question of what kind of people we are looking at. Are they rural? Are they urban? Are they immigrants? Are they aboriginals? There's a whole set of further questions that constantly need to be asked to do a proper analysis of these questions.
Then you also need to ask the fundamental question in the end. What are the unintended consequences that are going to result from this? And we're finding, more and more, that there are unintended consequences, things that were not initially thought about, that need to be asked.
These are the questions that need to be asked, and any good minister, I assure you, will ask these questions, and any good public servant will see that, to the best of their ability, the analysis can be undertaken so that these questions can be addressed before the policy is actually decided upon and announced.
