As demographic structures shift dramatically across the globe, many developed and developing countries are simultaneously confronting the dual pressures of a shrinking labor force and a rising old-age dependency ratio. One perspective argues that governments should prioritize their limited fiscal resources toward policies that extend the retirement age and encourage immigration to sustain economic vitality; another voice warns, however, that such an approach may neglect the medical care and social dignity of the elderly, potentially triggering a crisis of intergenerational equity. Discuss both positions and propose how governments should balance economic sustainability with social well-being, using specific country or regional examples to support your argument.
