Brash in a Spectator interview two weeks ago;
In the Spectator interview, he said that his overriding objective was to make New Zealand wealthy again. He also admitted that the party's education for the 2005 election was "in some respects" a quasi-voucher system. He said he wanted "real" welfare reform. "There has been a big exodus of people from unemployment benefit to non-work-tested sickness and invalid benefit. We were going to take a much firmer view to avoid people getting trapped in these demoralising dependency traps."
Brash always understood how big a problem welfare dependence is for this country. Google Don Brash and Welfare and you get oodles.
Google John Key and Welfare and there is almost nothing. Sure Key hasn't had the portfolio or been leader but Brash was talking about the need for reform when he was Reserve Bank Governor! It was always crystal clear what concerned Brash but I have no idea what John Key is passionate about changing.
In terms of acting on welfare, Bill English is the better bet.
