Band 8 model answer

Governments across the world face difficult choices in allocating limited healthcare budgets. I strongly agree that greater investment in preventive medicine represents a wiser use of public funds than concentrating resources on treating established illness, though a modest treatment infrastructure must always be maintained.

The case for prevention rests primarily on economics and scale. Treating a patient for advanced type-two diabetes, for instance, involves decades of medication, specialist consultations, and potentially costly complications such as renal failure or amputation. By contrast, funding community exercise programmes, subsidising fresh produce, and running public education campaigns can delay or entirely prevent such conditions in large segments of the population. When governments act upstream, they reduce the total burden on hospitals and free resources for genuinely unavoidable emergencies.

There is also a compelling equity argument. Preventable diseases disproportionately affect lower-income communities, where poor diet, sedentary work, and limited health literacy converge. State-funded vaccination drives, screening programmes, and health visitors can reach these groups in ways that market-driven treatments never will. Countries such as Finland, which invested heavily in cardiovascular disease prevention from the 1970s onwards, achieved dramatic reductions in heart disease mortality precisely because they targeted modifiable risk factors before illness took hold.

Critics reasonably point out that prevention cannot replace treatment entirely. Genetic conditions, accidents, and infectious outbreaks require skilled clinical response regardless of how well a population looks after itself. A purely preventive budget would therefore be irresponsible.

Nevertheless, the balance of evidence favours shifting more spending towards prevention. Treating illness after it arises is both more expensive and less effective than stopping it from developing in the first place. Governments should therefore prioritise prevention while retaining a well-funded safety net of curative services.
