I have watched that documentary a couple of times and I absolutely love it.

The think big projects are what I mean by good ideas. Especially the dams, steel and aluminuim facilities (that provided employment and cheaper goods for many years).

But the tinkering with the economy and fucking over the balance of payments wasnt helpful. Though I think he genuinely was trying to help the working people in the short term but couldnt handle the decisions that needed to be made for the long term solution.

Now New Zealand is seen as a champion of economic shift where we went from one of the richest in the 1950's
to almost bankrupt in the 80's because muldoon and co. were still thinking with ideas from the 50's
and now to one of the best performing economies in the world again.
