Ken Henry on tax reform

If the tax structure from early last century prevailed today, we would have to raise $40 billion from excise and $230 billion from tariffs to meet today's revenue demand. At that rate the excise on a schooner of beer would be around 7 times what it is today. And I shudder to think how much a television set would cost.

That's Treasury head Ken Henry, speaking on lessons from past tax reform experience. Henry is chairing the review of Australia's tax system and he singles out road pricing to address congestion as a perfect candidate for reform:

When vehicles drive on a congested road they impose costs on other drivers. Each driver thinks of their own need to get to their destination, not considering how, by taking up space on the road, they impinge on the ability of other drivers to do so. There is no means for one driver to coordinate with others, to bargain about who should have priority, so that they can all be better off. This results in a predictable 'tragedy of the commons' which is estimated to waste around $9 billion a year in avoidable congestion costs, increasing to around $20 billion by 2020. Such costs will only increase with faster population and economic growth.

Worth a read.
