How important is it for governments to plan for the future?

I think long-term planning is crucial for governments because it prevents short-sighted decisions that might harm future generations. Take Shanghai's metro system expansion as an example-they planned lines years in advance, which reduced overcrowding now that the population has grown. Without that foresight, daily commutes would be much more chaotic. That said, plans need some flexibility-like when unexpected tech changes happen-because sticking rigidly to old blueprints can waste resources. It's about balancing vision with adaptability.
