Although ACT, and to a lesser extent National, argue that lower taxes will make New Zealand more competitive with Australia and the U.S, they fail to appreciate that New Zealand suffers from serious under investment in key areas such as transport and energy infrastructure which are at least as important to economic outcomes.
Since 1984 an increasing percentage of government spending has gone into health and welfare. This is largely unavoidable because of the aging profile of the population. Furthermore, the elderly are very politically powerful and significant government cuts in health spending or pensions would arguably be political suicide. To pay for this increased health spending the government has reduced spending in other areas such as transport and defence. New Zealand now has no air force to speak of and is unable to cooperate in serious military exercises with its former ANZAS partners- Australia and the U.S.
Recently, the government has increased transport spending, but major projects are now subject to increasing costs and delays, thanks in part to the Resource Management Act. Cuts in transport spending reduce productivity since the more time people spend travelling, the less time they spend working and completing tasks. This is particularly true for tradesman and small business owners. Long journey times, to and from work, also make jobs less attractive to employees and are thus a negative factor in the competition for skilled workers in the international job market. Subsequently, it is counter productive for the government to cut transport spending so as to lower income tax rates.
New Zealand’s rate of spending on research and development has been very poor since 1984, although the Labour Government is now beginning to address this. Research and development spending is a major factor in the international competitiveness of New Zealand companies and a big factor in the nation’s brain drain since clever people like the interesting jobs that R and D spending generates.
In the energy sector there has been little provision for New Zealand’s growing population, with Auckland now increasing prone to power failures. In theory the country could save substantial amounts of power through power conservation. Most older homes and commerical buildings in New Zealand are very poorly insulated, so there is a lot of potential for the government to encourage energy conservative through incentives. However, the government currently spends very little on energy conservation.
Overall there is very little leeway in New Zealand for cutting taxes since any cuts in energy, transport, or research and development spending would be counter-productive, while cuts in other areas would be very politically unpopular. Similarly, defence spending has already been cut to the bone and it would be foolish to cut it any further. In practice, National realises that significant tax cuts are unrealistic and most of its proposals for tax cuts are modest, while Act is getting little electoral support for its flat tax proposals. Cutting taxes may have worked in the 1980s but it just isn’t going to have a major impact today.
There is however, a lot of scope for debating how tax is weighted since many economists are now debating the merits of income tax compared with taxes on capital, as well as the feasibility of taxes on pollution. In the future, political parties may decide to appeal to voters by reducing income tax and increasing other taxes but this appears unlikely at present.
Since serious tax cuts are no longer politically feasible, New Zealand’s die hard libertarians should campaign over other issues such as- political correctness in education, the debt culture, welfare mis-management, and the red tape which frustrates small businesses as well as large contractors involved in infrastructure projects.
