The Greens know that we must learn lessons from the past, because a house price crash could, in fact, lead to a credit crunch and higher unemployment, with people losing their houses and, over time, wealth concentrating even more so at the top end of town. This cannot go on, but we cannot let these potential issues scare us into ignoring the problem and potentially making that risk far worse were it to just happen to us. The Government must act and intervene to protect people as we take the heat out of this housing market.
