Let me try to explain what has been said. When one looks at a renter, it's clear you have income from outside and then you pay out rent, and that's a living expense. With a homeowner the situation is a little bit different. A homeowner has cash income and then, by virtue of owning their home they receive non-cash income, which is the money they don't have to pay out for the rent of their home. That's a notional income. We in the tax system often tax non-cash income. There are certain benefits people get from employers that are taxed. In some of the tax systems around the world they tax that notional income. It is a distinct benefit to the homeowner that the homeowner, instead of putting $200,000 in shares, bringing an income, paying tax on that and then paying a rent, puts $200,000 into their own home, pays it all down for cash. Then, under our tax system, it shows up as having no income from that $200,000 and so pays no tax on that. So they get to enjoy a home worth, say, $2,000 a month, whereas when you run it through the tax system you get $2,000 of income. If you're at the 50% bracket you pay $1,000 in tax, so you'd only have $1,000 left to pay your rent. That's the discrepancy. Certainly it is a notional income. It is something people are not used to looking at, but it is a huge benefit to homeowners. When one is looking at all the tax expenditures the system includes, that is the biggest amount, frankly, because it's ongoing every year. I'm a homeowner myself. I'm glad I have that income from my house that I don't have to pay tax on.
