Mike Williams: National's unwise double down on 'trickle down'

This tax policy, announced by National earlier this year would reduce Government income annually by more than $3 billion.

As in previous years National's tax-cutting policy is again heavily skewed in favour of the already well-off.
Luxon, just counting his parliamentary salary (not including income from his many rental properties) would be $18,000 a year better off, while those folk on $40,000 would get an increase of $2 a week.
Since the 1990s the National Party has developed a fixation with tax cuts despite Don Brash advocating an extreme version of this approach and going on to lose the 2005 General Election.
There are several reasons for this preoccupation. First, many National Party activists apparently believe in the "trickle down effect".
This amounts to faith that if you make well-off people even richer, much of this wealth will "trickle down" into the hands of the less well-off.
This belief has no basis in research whatsoever.
Extra income going to the already rich will tend to be piled up, spent on overseas trips, or put into the stock market.
If you are already having your hair done every Friday, it's unlikely you'll repeat the exercise on Mondays as well.
Very little will end up in the hands of bus drivers, cleaners, or nurses.
Second, a tax-cutting policy will often be greeted with poll support, at least until the voters work out that the necessary spending cuts may well hit policies and programmes that they value.
This is what happened to Don Brash's tax-cutting 2005 campaign. When the roughly 200,000 state house occupants realised that National, if elected, would increase their rents by abolishing income-related rents and bringing back market rates, they turned out to vote in unprecedented numbers and re-elected the Labour-led Government for a third term.
Third, a policy of reduced taxes for the rich encourages rich people to make large donations to National.
Both Luxon and Willis have been coy about what spending will be cut or which Government income will be increased to finance its tax policies.
They talk of trivial sums or fudge answers with references to unspecified wasteful spending.
We do, however, have a very useful insight into National Party thinking by examining how the John Key National Government funded similar tax cuts for the rich in their term in government.
This Government implemented a number of policies which were either ruled out or went unmentioned during the 2008 election campaign.
A significant money grab was the increase in GST from 12.5 per cent to 15 per cent in 2010. A GST increase had been specifically ruled out by John Key and National before the 2008 election.
As people on low incomes spend virtually every dollar they receive, this means poor people paid for the tax cuts for the already wealthy.
In addition, National in government abolished the KiwiSaver sign-up bonus of $1000 and cut government contributions, despite John Key's promise that there wouldn't be "radical changes".
If you, like most working Kiwis, have a KiwiSaver account, that National Government's duplicity cost your retirement fund a lot of money.
The Key Government's treatment of Kainga Ora laid the groundwork for the housing crisis that the current Government struggles with. National sold off state houses and treated Kainga Ora as a cash cow, grabbing $500 million in "profits" from tenants during their term.
Their string of "zero budgets" saw road-building investment frozen and hospitals run down.
This time when National talks about cutting tax, make very sure you know who's going to pay before you cast your vote.
