I think the most important thing is that this information is really outdated. It was done by Neil Brooks, who is a real tax expert. To my knowledge, nothing like that has been done since by government or others outside government. I think there are pieces of it, but to us this is one of those governance accountability and transparency issues.
It makes the point that there are so many income tax credits and deductions and things that go out for so many different things. If governments over time generally put these out as direct programs and said “You're low-income, and under this program you're going to get $5; and you have a higher income, so we're going to give you $50”, people would say that's crazy; you can't do that. But in the tax system those kinds of things happen all the time.
