This data tells more of a story than I expected. Firstly, New Zealand has not been catching up with the USA. Japan stopped catching up with the USA in 1990. Canada has been drifting away from the USA for a good 30 years now in labour productivity.
Australia has not been catching up with the USA much at all since 1970. It has maintained a pretty consistent gap with New Zealand despite all the talk of a resource boom in the Australia; you cannot spot it in this date are here.
Germany and France caught up pretty much with the USA by 1990. Oddly, Eurosclerosis applied from then on terms of growth in income per capita.
European labour productivity data is hard to assess because their high taxes lead to a smaller services sector where the services can be do-it-yourself. This pumps up European labour productivity because of smaller sectors with low productivity growth.

The Washington Centre for Equitable Growth have joined the Wall Street Journal in falling for that dodgy OECD hypothesis about rising inequality holding back economic growth.
The chart below shows stark differences between egalitarian Sweden and France, and the more unequal UK since 1970 in departures from a trend growth rate of 1.9% in real GDP per working age person, PPP.

In the above chart, a flat line is growth at the same rate as the USA for the 20th century, which was 1.9% for GDP per working age person on a purchasing power parity basis. The USA’s growth rate is taken as the trend rate of growth of the global technological frontier. A falling line in the above chart is growth in real GDP per working age person, PPP, at below this trend rate of 1.9%; a rising line is above trend rate growth for that year.
- Sweden really had been the sick man of Europe until it turned its back on high taxing, welfare state socialism in the early 1990s.
- France has been in a long decline so much so that the global financial crisis is hard to pick up in the acceleration in its long decline in the mid-1990s.
Britain did very well, both under the neoliberal horrors of Thatcherism and the betrayals by Tony Blair of a true Labour Party platform. The UK grew at above the trend annual growth to 1.9% for most of the period from the early 1980s to 2007.
Neither France or Sweden, despite their egalitarian economies, kept up with the US growth rate since 1970. Under the OECD’s hypothesis, if France and Sweden had been more unequal, their trend growth rates would have been even more appalling since 1970.

Unlike the USA, the German, Italian, British and French equilibrium unemployment rates all show fluctuations that reflect changes in their underlying economic circumstances and labour market reforms. The case of the British, the rise of the British disease and Thatchernomics. The case of German, its equilibrium unemployment rate rose after German unification and then fell after the labour market reforms of 2002 to 2005.

There are large differences in unionisation rates between the three countries. France has always had low levels of unionisation which halved since the 1970s. Italy had a sharp boost in union membership in the number of unions in the 1960s and 70s. This may have been associated with increased urbanisation. Union membership rate stayed pretty high in Italy ever since with a small taper downwards. Germany had stable unionisation rates prior to German unification after which the numbers about halved up in a slow taper.
