Interesting to notice that in New Zealand and the USA after these increases in marginal tax rates on single taxpayers, their economies slowed down. What appears to have happened is a number of people reached the next income tax marginal tax rate threshold.

The great divergence in average and marginal tax rates in New Zealand since 2000

21% would have been a good guess of the average and marginal tax rates of the New Zealand single earner or couple including with children and even a second earner in 2001. New Zealand average and marginal tax rates have been on a wild ride since the year 2000.

Sources: OECD StatExtract and OECD Taxing Wages.
As the above chart shows, while the average tax rate of a single earner with no children is pretty much unchanged at about 20%, he now faces a marginal tax rate of 30% or more rather than 21% in 2001.
For a married couple with one income, as the above chart shows, their average tax rate has been about zero for a good 10 years now but their net marginal tax rate is a good 50% or more because of abatement rates on family tax credits, which is a skewed incentive situation. A large income effect from the family tax credit encourages the consumption of leisure but a high marginal tax rate discourages working more.

Sources: OECD StatExtract and OECD Taxing Wages.
For two earner couples, their average tax rates have fallen because of family tax credits but their marginal tax rates have gone through the roof as the above chart shows. A tax system that discourages quite severely any further work or investment in human capital by average earners may have adverse effects on the long-term trend growth rate of New Zealand.

In 2000 in New Zealand, the marginal tax rates of single earners, married couples and dual income couples were 21%.
Sources: OECD StatExtract.and OECD Taxing Wages.
Net personal marginal income tax rates increased:
- to 51% for one earner couples with two children in 2001 and stayed up above 50% until 2014; and
- to 33% for single earners with no children in 2004 because income growth pushed them into the next tax rate bracket which then dropped down to 30% in 2011.
Sources: OECD StatExtract.and OECD Taxing Wages.
Net personal marginal income tax rates increased:
- to 33% in 2004 for two earner couples with the second earner earning 33% of average earnings and then increased to 53% in 2006 and stayed high thereafter;
- to 33% in 2004 for a two earner couple with the second earner earning 67% of average earnings and then increased further to 53% in 2006 and stayed high until 2014 when their marginal income tax rate dropped to 30%; and
Sources: OECD StatExtract.and OECD Taxing Wages.
These large increases in marginal tax rates on single earners and families coincided with a slowing of the economy in about 2005. The economy started to pick up again when there were tax cuts introduced by the incoming National Party Government. Is that more than a coincidence?

A flat line in the above figure is growth at the trend growth rate of 1.9% of the USA in the 20th century. A rising line is above trend growth for that year while a falling lined is below trend rate in GDP per working age person.
In the lost decades of New Zealand growth between 1974 In 1992, New Zealand lost 34% against trend growth which was never recovered. There was about 13 years of sustained growth at about the trend rate or slightly above that between 1992 and 2005. The entire income gap between Australia and New Zealand open up during these lost decades of growth between 1974 and 1992.

Australia grew pretty much in its trend rate of growth since the 1950s. The so-called resources boom is not visible such as showing up as above trend rate growth.

“Family silver’ looking a bit tarnished

In the editorial today in the Dominion Post on the Solid Energy fiasco, the editorial writer made quite an extraordinary statement:
“Ideologues of the Right will claim that the whole sad fiasco shows the dangers of the state getting into business. This is simple-minded. Not all SOEs have ended up hundreds of millions of dollars in debt. Some SOEs have been well run; some have not.”
It is absurd to claim that making a $20 million net profit on a portfolio of $30 billion in state owned enterprises in 2013 is some sort of reasonable investment for the taxpayer.
Opponents to the sale of minority shareholdings in a few state owned assets would have us believe that the government is selling the family silver.
Treasury’s annual portfolio return shows that silver isn’t returning much:
Government businesses with assets worth $45 billion made a total net profit of just $20 million in the year to June 30, according to the Treasury’s annual portfolio report.
The assets don’t include Meridian Energy, Air New Zealand and Mighty RiverPower, which were partially privatised, but cover troubled entities like KiwiRail, Solid Energy and New Zealand Post, which are all struggling to make their business models work.
The annual review covers Crown-owned assets valued at $125b.

PRESS RELEASE: Greenpeace Parliament Climbers Convicted of Trespass bit.ly/1DRfKMG #realclimateaction http://t.co/sxRokpwRNk—

The Greenpeace vandals who trespassed at Parliament, climbing up to put signs down the front in flagrant disregard of the most ample possible options for peaceful protest right outside at least had the integrity to plead guilty. That shows some sort of fidelity to law and an acknowledgement that what they did was a criminal offence.
John Rawls makes the point that the purpose of civil disobedience is not to impose your will upon others but through your protest to implore them to reconsider their position and change the law or policy you are disputing.
Rawls argues that civil disobedience is never covert or secretive; it is only ever committed in public, openly, and with fair notice to legal authorities. Openness and publicity, even at the cost of having one’s protest frustrated, offers ways for the protesters to show their willingness to deal fairly with authorities. Rawls argues:
- for a public, non-violent, conscientious yet political act contrary to law being done (usually) with the aim of bringing about a change in the law or policies of the government;
- that appeals to the sense of justice of the majority;
- which may be direct or indirect;
- within the bounds of fidelity to the law; and
- whose protesters are willing to accept punishment. Although civil disobedience involves breaking the law, it is for moral rather than selfish reasons; the willingness to accept arrest is proof of the integrity of the act.
Rawls argues, and too many forget, that civil disobedience and dissent more generally contribute to the democratic exchange of ideas by forcing the champions of dominant opinion to defend their views.
Legitimate non-violent direct action are publicity stunts to gain attention and provoke debate within the democratic framework, where we resolve our differences by trying to persuade each other and convince the electorate.
Too many acts of non-violent direct action aim to impose their will on others rather than peaceful protests designed to bring about democratic change in the laws or policies of the incumbent government. That ‘might does not make right’ is fundamental to the rule of law. As United States Supreme Court Justice Antonin Scalia said
The virtue of a democratic system [with a constitutionally guaranteed right to free speech] is that it readily enables the people, over time, to be persuaded that what they took for granted is not so and to change their laws accordingly..
Both sides passionately but respectfully attempt to persuade their fellow citizens to accept their views. Win or lose, advocates for today’s losing causes can continued pressing their cases, secure in the knowledge that an electoral loss today can be negated by a later electoral win, which is democracy in action as Justice Kennedy explains:
…a democracy has the capacity—and the duty—to learn from its past mistakes; to discover and confront persisting biases; and by respectful, rationale deliberation to rise above those flaws and injustices…
It is demeaning to the democratic process to presume that the voters are not capable of deciding an issue of this sensitivity on decent and rational grounds.
The process of public discourse and political debate should not be foreclosed even if there is a risk that during a public campaign there will be those, on both sides, who seek to use racial division and discord to their own political advantage. An informed public can, and must, rise above this. The idea of democracy is that it can, and must, mature.
Freedom embraces the right, indeed the duty, to engage in a rational, civic discourse in order to determine how best to form a consensus to shape the destiny of the Nation and its people. These First Amendment dynamics would be disserved if this Court were to say that the question here at issue is beyond the capacity of the voters to debate and then to determine.
John Rawls’ view that fidelity to law and democratic change through trying to persuade each other is at the heart of civil disobedience reflects the difference between the liberal and the left-wing on democracy and social change as Jonathan Chait observed this week:
Liberals treat political rights as sacrosanct. The left treats social and economic justice as sacrosanct. The liberal vision of political rights requires being neutral about substance.
To the left, this neutrality is a mere guise for maintaining existing privilege; debates about “rights” can only be resolved by defining which side represents the privileged class and which side represents the oppressed…
Liberals believe that social justice can be advanced without giving up democratic rights and norms. The ends of social justice do not justify any and all means.
