In many of today's major cities, young people are relocating to suburbs or towns at record speed, while city centers are increasingly populated by older residents and short-term occupants. In response to this trend, some argue that city administrators should prioritize investments in measures to attract young families back to urban areas, while others contend that such resources should instead be directed toward improving the quality of public life for the elderly, who serve as the cornerstone of long-term stability in city centers. Which position do you support? Please elaborate with specific reasons and examples.
