New work by Chris Ball and John Creedy shows substantial *declines* in NZ inequality.
You really are still fighting the 1990 New Zealand general election election if Max Rashbrooke makes more sense than you on the good old days before the virus of neoliberalism beset New Zealand from 1984 onwards.
Maybe 65% of the population of those good old days before the virus of neoliberalism. were missing out on that broadly egalitarian society championed by Bryan Bruce.
As is typical for the embittered left, the reactionary left, gender analysis and the sociology of race is not for their memories of their good old days. New Zealand has the smallest gender wage gap of any of the industrialised countries.
The 20 years of wage stagnation that proceeded the passage of the Employment Contracts Act and the wages boom also goes down the reactionary left memory hole.
That wage stagnation in New Zealand in the 1970s and early 80s coincided with a decline in the incomes of the top 10%. When their income share started growing again, so did the wages of everybody after 20 years of stagnation. The top 10% in New Zealand managed to restore their income share of the early 1970s and indeed the 1960s. That it is hardly the rich getting richer.

Both the proletariat and the middle class are withering away these days thanks to capitalism and freedom.
