Most of us are too young to see it, but a big way the federal government affects our lives is through its system of compulsory superannuation. As you get older and retirement becomes a lot less distant, you begin to realise that the rules of super – and successive governments’ tinkering with those rules – will have a significant impact on the up to 30 years of your life after you stop working.

When the age pension was introduced more than a century ago, many men didn’t live long enough to reach the age of eligibility, 65. But our greater prosperity, improvements in public health and advances in medical science have changed all that.

Although the age of pension eligibility – for women as well as men – has been raised to 67, and no doubt will reach 70 one day, our longevity has increased by more, making it possible, particularly for women, to live up to 30 years in retirement.

But the introduction of compulsory super in the early 1990s now means that people retiring after about 2030 will do so with so much super that their eligibility for the age pension will be between limited and non-existent.

Since the introduction of that new system, almost every government has changed it. Why? Because the new compulsory system was bolted onto an old voluntary system of tax concessions that proved to be far too generous to high-income earners and too mean to lower-income earners.

Everyone knows the age pension costs the government a lot of money. What many don’t realise is that the tax concessions attached to super contributions and to the subsequent earnings on those contributions also cost the government a lot in the form of income tax collections forgone.

So, all the super changes since those made by the Howard government in 2007 (which gave well-off Baby Boomers like me a huge free kick) have aimed to reduce super’s cost to the budget by reducing the tax breaks going to high earners.

Take my word, there’ll be many similarly motivated changes to come. Those made last year by Treasurer Jim Chalmers won’t be the last.
