Many countries encourage their citizens to retire later than in the past.

In many countries the government has increased the age when people can receive a pension. This decision has some advantages, but also several disadvantages.

The first advantage is economic. People today live much longer than fifty years ago, so if everybody retires at sixty, the state must pay a pension for twenty-five or thirty years. When people work five years more, the government collects more taxes and pays fewer years of pension, so the system does not collapse.

Another advantage is for the person. Some people feel useless and become depressed when they suddenly stop working, and they lose contact with their colleagues. If they continue working, they keep their routine, they stay active and they also earn more money for their old age.

However, there are serious disadvantages. Not all jobs are the same. An office worker can easily work until sixty-seven, but a builder or a miner has back problems and cannot do heavy physical work at this age. For these people, a later retirement means several years of pain or of unemployment.

In addition, older workers occupy positions that young people need. If a company does not have free places, young graduates cannot start their career, and youth unemployment increases.

In conclusion, working longer helps the state budget and keeps people active, but it is unfair for people with physically difficult jobs and may create problems for young workers.

Many governments now encourage or require citizens to work beyond the retirement ages set in previous generations. The arguments in favour are substantial, but so are the objections, and both depend heavily on who is being asked to work longer.

The fiscal case is the strongest. Life expectancy has risen by roughly a decade in many countries without a corresponding change in retirement age, so pensions that were designed to fund perhaps a decade of retirement now fund two or three. Each additional working year both adds tax revenue and removes a year of payments, which is why almost every government facing an ageing population has reached for this lever.

There are individual benefits too. A significant proportion of people find that abrupt retirement removes structure, purpose and daily social contact simultaneously, and report declining wellbeing as a result. Continued employment maintains income, routine and status, and organisations retain expertise that takes decades to accumulate.

The principal objection is that a uniform age ignores what different work does to a body. Someone who has laid bricks or nursed patients since sixteen arrives at sixty-five in a very different physical condition from someone who has worked at a desk, and asking both to continue for three further years is asking very different things of them. The unfairness deepens when life expectancy is considered: manual workers on lower incomes tend to die earlier, so they contribute for longer and collect for a shorter period.

A further difficulty is that willingness is not sufficient. Workers over fifty-five who lose a job face substantial hiring discrimination, so raising the pension age without addressing this leaves some people neither employed nor entitled to a pension.

In conclusion, later retirement is fiscally necessary and suits many people well, but applied uniformly it transfers the heaviest burden onto those with the hardest jobs and the shortest lives.

Raising the retirement age is among the few policies that is simultaneously unavoidable and difficult to defend, and the reason is that it is a single instruction issued to people whose working lives have almost nothing in common. Its advantages are real and general; its disadvantages are real and concentrated, which is a much harder combination to manage than a straightforward trade-off.

The case in favour begins with arithmetic. Pension systems were designed when retirement lasted perhaps a decade; life expectancy has since risen by roughly ten years without a matching adjustment, so the same contributions now fund two or three times the payout period. Each extra year of work therefore improves the position twice over — one more year of revenue, one fewer of expenditure — and no other available lever has that property.

There is also a genuine individual argument, which advocates state too rarely because it sounds convenient. Retirement removes income, routine, purpose and most daily social contact at the same moment, and a substantial minority of people experience that as a loss rather than a release. For them, continuing to work is not an imposition but a preference the previous system denied.

The objection that matters is not that people dislike working longer but that identical rules produce unequal sacrifices. Someone who began physical labour at sixteen reaches sixty-five with a body that has absorbed fifty years of it, while someone who entered an office at twenty-three arrives comparatively intact. Healthy life expectancy — as opposed to life expectancy — differs by well over a decade between the richest and poorest groups in many countries, which produces a genuinely regressive outcome: those with the hardest work contribute for the longest and draw a pension for the shortest time, because they die sooner. A uniform increase quietly redistributes from the people who can least afford it.

A second practical objection is that intention does not create employment. Workers over fifty-five who lose a job face significant hiring discrimination, and raising the pension age without addressing that leaves people stranded between employment they cannot obtain and a pension they cannot yet claim — an outcome that saves money precisely by inflicting hardship.

One frequently raised disadvantage should be set aside: the claim that older workers occupy jobs the young need assumes a fixed number of jobs, which economies do not have. Employment is not a cake, and periods of high older-worker participation have not coincided with elevated youth unemployment. The serious objection is distributional rather than competitive — the case for later retirement is strong, and the case for applying it identically to everyone is not.
