Every con needs a mark who thinks they are being rescued instead of fleeced. Carnival grifters used to pick the gullible one out of the crowd, run the game and then chalk them on the back afterwards - a literal mark. Every other operator knew that one had already been worked and to leave them alone. Young Australians, planning for their futures, have effectively been chalked. Labor picked them out of the crowd 10 months ago, ran the housing game and is now standing over the wreckage.
