An organiser addresses the Occupy Christchurch group protesting the excesses of global capitalism at the Bridge of remembrance in 2011.

Capitalism is not a force for good but a mechanism for the few to amass wealth at the expense of the many writes former Christchurch mayoral candidate John Minto.

OPINION: It was sad reading Stephen Hickson's defence of capitalism.

Sad because capitalism has delivered so much outright misery to so much of humanity over the last 300 years that it's hard to believe anyone could be so blinkered.

Joseph Johnson John Minto speaks during The Press Christchurch mayoral candidates debate in 2016.

Capitalism was never intended to meet human needs. It was developed and maintained by the wealthy and powerful, and supervised by their political representatives, to make profits.

Small wonder then that capitalism creates a vast quagmire of problems in its wake – no more so than in New Zealand.

Capitalist market failure is everywhere. Desperate housing shortages, poverty incomes, environmental destruction, sky-high electricity prices, mental health service breakdown, child poverty – you name it – markets have failed us across the board.

When 41,000 people are living in overcrowded homes; cars and vans; cockroach infested caravans and under bridges then the housing market has failed.

Left to itself, capitalism will only ever provide a cardboard shack for a family on a low income.

David Hallett Occupy Christchurch camped in Hagley Park for several months during 2011/12 as part of a protest against global capitalism.

On a global scale we see the same pattern. Planet Earth produces enough grain each year to comfortably feed the entire human population but through the capitalist drive for profit, half that grain is used to feed animals to provide meat for middle class appetites while tens of millions of our fellow human beings starve.

Likewise the big American drug companies who claim they need to charge exorbitant amounts for new drugs because of the huge cost in developing them, spend much more money on advertising than they do on research and development.

To some extent it is a failure of governments to intervene in markets which exacerbates the negative impacts of capitalism, as Hickson suggests, but the last 30 years of unfettered capitalism has shown us its true nature.

Working people's share of our national income has gone down dramatically while the share of income going to profits has increased. In other words, those who do the work to produce the wealth are getting less while those who live off wealth produced by others have had big increases in unearned income.

Deep in the belly of the capitalist beast, the US, there are 45 million Americans (15 per cent of the population) living below the poverty line while in New Zealand we have one in four of our children living similarly in what once was called "God's own country".

Hickson is right to suggest taxes and regulations can help ease the worst problems with capitalism but this is like putting band aids on a cancer. Hickson gives the example of the top 11 per cent of income earners paying 48 per cent of total income tax while the poorest 49 per cent pay only 9 per cent of income tax.

However, no single figure on tax could be more misleading. Hickson ignores GST and the fact little or no tax is paid on the unearned income of the wealthy via such windfalls as capital gains, dividends or inheritance.The poorest 10 per cent of earners pay 14 per cent of their incomes (after housing costs) on GST while the top 10 per cent pay less than 5 per cent of their income on GST. It is a tax that falls heaviest on those on the lowest incomes.

When one takes GST into account as well as income tax, a worker on the minimum wage pays around 26 per cent of their income in tax while the Prime Minister will pay about 35 per cent of her income in tax. For someone on the rich list the figure will be less than 5 per cent.

According to IRD, half the wealthiest 150 New Zealanders declare incomes of less than $70,000 for tax purposes. The rest of their massive income is for the most part untaxed. In reporting on the 2017 rich list earlier this year, National Business Review editor Duncan Bridgeman said "I think it's continued boom times for the rich, the rich get richer and the rich are having a really successful period at the moment."

According to Bridgeman New Zealand's super wealthy increased their wealth by $7 billion over the past year to a total of $80 billion.Think about that for a moment. This wealth is not created from thin air. It is made from manipulating the wealth created by working people.

In other words, you and I and every person living in New Zealand has provided $1500 more this past year so these 150 people could build a bigger pile of unearned income. And they pay next to no tax on it.

So why does a worker on the minimum wage pay a much higher tax rate than a rich lister? Because rich listers have far greater political influence than the rest of us.

Capitalism is not the force for good its advocates claim. At heart it's a mechanism for the few to amass wealth at the expense of the many.

Human beings are social beings. We are more naturally co-operative than competitive but capitalism is based on the reverse.

The alternative is socialism (not the totalitarian state capitalism of the old USSR or China – misnamed as socialist or communist) whereby we cooperate together to ensure everyone has the ability to live lives of dignity and self-respect. That's where our best future lies.

In the meantime the new government says it intends to set up a working group on taxation to come up with a fairer system. It's long overdue but I'm not holding my breath.

We will know from the outset by the makeup of the working group and its terms of reference whether the government is serious about reducing poverty and inequality and giving everyone a fair go.

Until then unfettered capitalism will continue to do its dirtiest work.
