The writing is on the wall in terms of the taxation/superannuation imbalance as our the demographics of most countries changes as a result of the post-war baby boom working its way through their populations.
I heard a very enlightening presentation by Gareth Morgan almost 20 years ago on this exact topic. As the population ages tax take will fall and the percentage of those in the workforce will decrease. This will be countered in a variety of ways including raising the retirement age, moving females back into the workforce, and increasing reproduction rates. All will result in the same increase in taxable population but on different time scales. The amount of capital tied up in domestic real estate is also a contributing factor and long term value of 'macmansion' scale homes will be at risk of severe devaluation as the demand for such houses decreases.
