Nicola Willis: Does he accept his policies are failing Jordan, who wrote to me saying, "I too struggle to afford food. Sometimes we only eat toast. I've had KiwiSaver since I was 16. Now I'm 30 and I don't have enough for a house deposit. I'm scared we're not going to have a home for my unborn baby.", and is he concerned that his policies are failing a generation of New Zealanders?
