The part of Winston's speech that really stood out and signified his direction was this:
Far too many New Zealanders have come to view today’s capitalism, not as their friend, but as their foe.
And they are not all wrong.
That is why we believe that capitalism must regain its responsible - its human face. That perception has influenced our negotiations.
And he's right. Capitalism is broken. Just look at housing, or poverty, or our shitty, low wage employment market - its just not providing for ordinary people (and that's not even getting into the ways it doesn't work around the environment). Whether it can be fixed or not is an open question, but I'm not going to fault people for trying. And if they manage to do something about the awful poverty (and associated cruelty) we tolerate, then maybe Metiria's martyrdom will have been worth it.
