of GDP?" Schroder asked."Is that a thing we would like because we'd rather earnings capital, we'd rather turn wealth into investible job-creating things? "Is it just a kind of polite conversation or is it really serious [enough] that we're prepared to re-set the expectations, the measures, the targets, the valuation process?" he asked.Mr Schroder said Australia's superannuation industry had a big role to play in this conversation.Alan Kohler wondered if the super industry could help Australians to purchase homes in more innovative ways, asking:"Have you thought about something like, when someone joins AustralianSuper, one of the options would be that you would build them a house and they would pay it off during the course of their working life, and so by the time they, as part of their super savings .. It's really important for us to have equity between members."And the next part is, you'd have to make sure that if we were to embark on something it's not just some sort of money-wasting white elephant."[But] I think there are ways to have 'super and housing,' not just 'super or housing'," he said.However, Mr Schroder said he was worried about the more extreme end of the political debate where people were saying that super should be used "for" housing.He said that's not what the discussion should be about."We need super and housing," he said."And I reckon there's a sweet-spot where super could fund things, or help fund things, that might help people be housed more quickly," Mr Schroder said.
