Australia Still Has Its Social Insurance Program for Retirement

Australia is frequently described as having a retirement system built on “superannuation”—its mandatory workplace retirement savings program. But superannuation is only one piece of the puzzle.

Australia, like most other developed countries, has a multi-pillar retirement system. (Notably, per the World Bank, no country in the world has fully eliminated its old-age pension even when it has instituted a national defined contribution policy.) 

The first component of Australia’s retirement system is the Age Pension, a publicly financed benefit that provides an income floor for older Australians who meet age and means-testing requirements. While it differs from Social Security in the U.S.—the Age Pension is means-tested and funded through general government revenue rather than dedicated payroll taxes—it serves a similar purpose: ensuring that older Australians have a basic level of retirement income. For those who qualify, the benefit is paid for life and is regularly adjusted to help keep pace with inflation and changes in wages, giving retirees a stable foundation even if their personal savings are modest.

“Australia did not replace its public insurance program for retirement with investment accounts. It built mandatory retirement savings alongside a government-backed retirement income program.”

The second component is superannuation, which requires employers to contribute a percentage of workers’ wages (currently 12 percent) into individual retirement accounts over the course of their careers. And while policymakers often describe Australia’s retirement income system as having three pillars—the Age Pension, compulsory superannuation contributions from employers, and additional voluntary personal contributions—in practice, the second and third pillars both flow into the same superannuation accounts.

In other words, Australia did not replace its public insurance program for retirement with investment accounts. It built mandatory retirement savings alongside a government-backed retirement income program. 

There’s another important difference that often gets overlooked. Australia’s superannuation balances didn’t appear overnight. They were built through hefty mandatory employer contributions made every payday over the course of Australians’ entire working lives. That’s fundamentally different from a one-time contribution made at birth—à la Trump Accounts—even if it has decades to grow.

Time in the market matters. But so do the size, consistency, and frequency of contributions. Thus, comparing Australia’s mature superannuation system to a childhood investment account is comparing two very different policies with very different objectives.

Whether in Australia or America, Assets Are Not Insurance

The broader debate also risks conflating two fundamentally different functions within a retirement system.

Investment accounts build assets. Social Security provides insurance. Those may sound similar, but economically they solve different problems for the household.

“One program helps people build wealth. The other ensures that wealth—or the lack of it—doesn’t determine whether someone can afford to grow old. Those are complementary goals, not competing ones.”

A traditional investment account is built to help someone accumulate wealth over time. It cannot guarantee that they won’t outlive their savings. It cannot promise inflation-adjusted income for life. It cannot eliminate longevity risk or market risk at the moment someone retires. (True, annuities and other lifetime income solutions—including those in 401(k) plans—can convert a balance into an income stream; but the amount of income one receives is ultimately based on how big the account balance is.) 

Social Security, by contrast, exists precisely because individuals cannot fully insure themselves against those risks on their own. Fundamentally, capitalist societies like the U.S., Australia, the U.K., and beyond have decided it is unacceptable for people who have earned less during their careers to age in poverty. Social Security is about protection, not prosperity.

One program helps people build wealth. The other ensures that wealth—or the lack of it—doesn’t determine whether someone can afford to grow old. Those are complementary goals, not competing ones.

Universality Doesn’t Mean Uniformity

One of the most promising ideas surrounding Trump Accounts is the possibility of automatic enrollment. Behavioral economics has shown us repeatedly that defaults matter.  Auto-enrollment dramatically increases participation, especially among lower-income families who are least likely to opt-in to financial programs on their own.

That’s a feature worth celebrating. But universal participation does not produce universal outcomes. Children will still experience different investment returns, receive different levels of family support, earn different wages throughout adulthood, and face different life circumstances—leading some to draw down funds well before they reach retirement age, which is part of the design of Trump Accounts and to be expected, if not encouraged.

By retirement, some accounts will be substantial. Others won’t. That’s precisely why a universal retirement system still needs a universal source of retirement income (as Australia reminds us). Asset-building programs create opportunity, but they don’t eliminate the need for a common foundation beneath everyone. And here in America, that means that the launch of Trump Accounts makes a compelling case for recommitting ourselves to—and strengthening—Social Security, even if the politics are hard. 

Protecting Households From a False Choice

The clearest evidence that Trump Accounts cannot substitute for Social Security, however, isn’t found in Australia. It’s found in the experience of millions of American households.

“That’s why the strongest retirement systems don’t force a choice between income security and asset building. They recognize that these are different objectives requiring different tools.”

Every month, Social Security delivers a guaranteed, inflation-protected paycheck for life. The average retired worker receives roughly $24,000 a year—nowhere near enough to fund a lavish retirement, but enough to ensure that a check arrives every month no matter what happens in financial markets or with inflation, how long someone lives, or whether they’ve exhausted their savings. No investment account can make that promise.

But Social Security wasn’t designed to do everything. It is intentionally paid out over time—a steady stream of income meant to cover ongoing, essential living expenses. It isn’t designed to replace a roof after a storm, buy a wheelchair-accessible vehicle, help a grandchild through college, or pay for a major long-term care expense. Those are the kinds of “chunkier” financial needs that require accumulated assets.

That’s why the strongest retirement systems don’t force a choice between income security and asset building. They recognize that these are different objectives requiring different tools.

Australia understood this. Its retirement system combines a public income floor with mandatory retirement savings and voluntary saving. The United States has long embraced a related philosophy through Social Security, voluntary employer-sponsored retirement plans, and personal savings. (Though here in America, we could do with a national approach to private retirement savings, given that 56 million private sector American workers still lack access to workplace retirement savings.)

Trump Accounts could become another layer in that system. If they help more families build wealth from birth, invest in themselves and their families, and enter retirement with greater financial resilience, that would be a meaningful achievement.

But don’t mistake them for a replacement for Social Security. The real lesson from Australia isn’t that public retirement income becomes unnecessary once people have investment accounts. It’s that retirement security is strongest when guaranteed lifetime income and accumulated assets work together—not in competition, but in partnership.
