But then, you come to this brightline test, the idea that if you buy and sell the same house within 10 years, you have to pay income tax at your marginal rate on any capital gain you make. Now, this is a very good lesson in tax policy, and, frankly, it's a good lesson for the National Party, because the National Party is jumping up and down, saying "Oh my god, the brightline test is now 10 years." Well, I remember someone saying in 2015, when the National Party introduced the brightline test, that this tax is the acorn of a capital gains tax. It's a measure that will grow from two years to five to 10 to 15 years. You watch, it will eventually apply to a wider range of homes. It's the acorn the National Party has planted that will grow into a full-grown capital gains tax. That was me in 2015. And guess what! Now it's a 10-year brightline test; we're halfway there already after just a few years.
