Bill Shorten was the unlikely hero of Waleed Aly's latest declamation lambasting the government's negative gearing policy, casting the opposition leader as the annoying neighbour we should all listen to.

Aly was in no mood to celebrate the Prime Minister Malcolm Turnbull's unwavering support of the negative gearing status quo, having previously stated he rents his family home because he and his wife can't afford to buy in Richmond.

"Economists agree, negative gearing pushes house prices up, contributes to making our houses some of the most expensive in the world, and if you're from generation X, Y, or a millennial, it's one of the reasons you've been locked out of the market," he said on The Project on Wednesday night.
