The problem could have been seen from another angle, which is that income tax—I claim no expertise in these matters, but it appears to be on income, and income is revenue minus expenses and interest is an expense. So if having income tax on income, which is revenue minus expense, with interest being an expense, hasn't created a bubble in the price of Toyota Corollas or desks or chairs or anything else that is freely available—and when the price goes up, people create more of them—maybe the problem with housing is not the tax treatment that applies to everything the same, but maybe the problem with housing was the supply of housing, or, to be really precise—because I know that the Minister loves to nerd out on this stuff—the supply elasticity of housing, and maybe if we fix the real problem, we'd be in a better space.
