The economist for the Council of Trade Unions Bill Rosenberg has produced some revealing data about the resumption of the declining share of labour income in the New Zealand economy in the most recent CTU economic Bulletin.
Since 2009, compensation of employees as a proportion of Net Domestic Income (NDI) fell from 61.2% to 59.1% in 2018 or about an average $2,122 of every wage and salary earner per year.
Not surprisingly, locally owned corporate profits went from 11.6% to 17.9% of NDI over the same period. If we add in overseas investors in, corporate profit is over a quarter of all income.
It is also worth noting that very high salaries (the top 0.1%) have gone from 13 times the average to 17 times and their share of wage and salary income has gone from 1.3 to 1.7 percent of all wage and salary income.
