In many cities today, the shortage of public spaces is forcing younger generations to compete with older demographics for limited recreational resources. Some argue that urban design should prioritize the needs of the young, as they represent the primary workforce of society's future; others insist that the well-being of the elderly better reflects the maturity of a civilization. How do you think urban planners should balance the interests of these two generations when allocating public spaces? Please state your position and support your argument with specific examples.
