The union movement posted two excellent charts during the last election showing how well things have gone since the 1980s economic reforms and their consolidation in the early 1990s.
The charts show that real wage growth returned in the early 1990s after the passage of the Employment Contracts Act and the consolidation of government finances. This was after two decades of wage stagnation in what the unions regards as the good old days.
Furthermore, as the union chart shows, the average incomes of the top 1% in New Zealand is a pretty stable for several decades. Whatever else is happening New Zealand, you cannot blame it on the top 1% because they are lazy. What increase there was in average top incomes in New Zealand was followed by the return of real wage growth in New Zealand and a long economic boom where the unemployment rate drop below 3.5%
The main bugbear is housing affordability which is a result of the Resource Management Act passed in 1993 as the union chart shows. The unions, the Labour Party and Greens all support the laws that result in this housing unaffordability.
